Sensor SignalConditioners

Powerfuland Flexible

yet Easy to Use

By David Grice Applications Engineer

Zentrum Mikrokelektronik (ZMDI) Dresden Germany

As demands increase for the number type and range of sensors in

almost every product category the difficulty of implementing them

increases proportionately This is especially true in th e automotive

arena driven by efficiency safety and emission requirements

Existing sensor technologies are inadequate to meet many of these

new and more stringent requirements spurring the development

of a new class of sensors based on micro-electro-

mechanical systems (MEMS) These new sensors

are smaller lighter more robust less ex pensive

and consume less power but they also

produce electrical signals that

are smaller and more nonlinear

than their bulkier counterparts

Next-Generation SO MANY SENSORS SO LITTLE TIME




As the quality of output from

transducers declines to meet

application demands system

requirements such as measurement range

accuracy speed and power consumption

continue to increase squeezing the

performance of sensor signal conditioning

(SSC) circuits from both ends and making

the task of designing them exponentially

more difficult

integrity level (ASIL) for automotive

applications These requirements

include detection and notification of

faults due to open or short circuits out-

of-range parameters aging sensors and

excessive temperature Additionally

the SSC must be able to monitor these

faults while tolerant of shorts to ground

or supply voltage supply overvoltage

conditions or reverse battery

connections

ldquoOne of the key features

of next-generation SSCs

is flexibilityrdquo

ldquoA highly efficient and powerful

reduced-instruction-set computercoordinates numerous control and

computational tasksrdquo

NEXT GENERATION TO THE RESCUE

In the same way increasing demands have

spurred a new class of sensors Zentrum

Mikroelektronik (ZMDI) is developing and

introducing the next generation of SSC

products and technologies to the sensor

marketplace This article describes some

of the most important and beneficial new

features of these new SSCs

FLEXIBILITY IS A BEAUTIFUL THING

One of the key features of next-

generation SSCs is flexibility The typesand combinations of physical quantities

measured for products are growing

rapidly and new SSCs must facilitate

fast development of complex sensor

modules with low component counts

and a user interface that is easy to learn

and use This requires a signal interface

that is configurable for a wide range of

signals and correction algorithms that

are much more complex than second

or third order polynomial curve fitting

offered by previous generations of

SSCs For example a single application

might require the conditioning of two

temperature inputs one being a diode

and the other a thermocouple and t wo

resistive pressure bridges with widely

varying output levels each of which

require linearization and calibration

Flexibility is not limited only to

signal types and ranges however

Another dimension of configurability

is required for the sequence of signal

processing tasks Typically some

signals must be acquired at a much

higher rate than others and the

quantization and correction algorithms

must be reconfigured quickly from

one measurement to another in a

programmable fashion In addition

to this sometimes it is necessary to

perform math operations between

signals like subtracting two pressure

inputs to generate a differential pressure

output The SSC mu st generate a user-

programmable sequence that samples

the inputs in a defined order and rate

correct each signal according to a user-

defined calibration algorithm and

combine the conditioned outputs into an

orderly stream of data

Finally flexibility must include the

number and type of output signals and

protocols Reliability safety weight

and noise constraints are also driving

the creation of innovative new output

protocols like single-edge nibble

transmission (SENT) for the automotive

industry Next-generation SSCs must

support new interfaces like SENT along

with the traditional analog one-wire and

serial interfaces such as I2Ctrade and SPI In

fact the SENT interface is output only

and requires an auxiliary interface like I2C

to configure and calibrate the SSC

Another important feature for next-

generation SSCs is the ability to perfo rm

self-testing and diagnostics

to meet critical safety standards

like the automotive safety

PUTTING IT ALL TOGETHER

Figure 1 shows the block diagram of a

next-generation SSC In this particular

case the SSC supports two temperature

inputsmdashone resistive one diodemdashand two

resistive bridge inputs The conditioning

signal chain includes sensor check and

common mode (SCCM) adjustment

multiplexing (MUX) programmable gain

(PGA) from 1 to 200 VV and an analog

to digital converter (ADC) with adjustable

sample rate and resolution from 12 to

18 bits

The SSC in figure 1 looks similar to other

SSCs that are presently available but

most of its potential and flexibility

lies in the calibration microcontroller

(CMC) A highly efficient and powerful

reduced instruction set computer (RISC)

coordinates the numerous control and

computational tasks necessary to provide

the tremendous amount of flexibility

required for next-generation SSCs The

controller also combines the multiple

output data packets into a structured

stream in a wide variety of formats that

can be either analog or digital

The cycle of tasks performed by the

RISC engine consists of three main

types measurement tasks conditioning

tasks and output tasks Measurement

tasks include operations that select

the MUX input and signal polarities the

gain and offset of the signal path the

speed and resolution of the quantizer

and auxiliary tasks such as auto-zeroing

gain stages The output values of

all the main measurement tasks are

stored in registers for processing by the

conditioning tasks These tasks range

from simple operations like shifting and

synchronization to basic math functions

such as add subtract multiply and

divide to complex functions such as

logarithms polynomial evaluation

spline curve fitting and digital filtering

Output tasks include synchronization of

data streams formatting packetizing

encoding error detection and safety

features like redundancy or inversion

The SSC shown in figure 1 provides for

up to 20 measurement tasks and 62

conditioning tasks enabling thousands

of different combinations of signal

processing sequences for each of the four

inputs The number of output tasks varies

greatly depending on the type of output

but for a complex protocol like SENT the

number can be in the dozens

MAKING IT EASY

However it is also vitally important that

the flexibility power and complexity

of next-generation SSCs do not

require a commensurate level of time

and resources for system designers

implementing them The example shownin figure 1 is a member of a product family

that is preconfigured by the manufacturer

for a specific application using firmware

All of the measurement conditioning

and output tasks are programmed

so that the designer need only focus

on determining gain resolution and

calibration coefficients for the correction

algorithm all of which are facilitated

by software that is easy to use and

Figure 1 An example block diagram of a nex t-generation SSC from ZMDI

ldquoOne thing that should

be flexible in next-gener

SSCs is the user interfa

consistent across the product line Special

use cases can be implemented easily in

firmware by the manufacturer should

the need arise but the standard factory

configuration will cover the majority

of designs Additional family members

of the product line are optimized for

different numbers and types of inputs

and outputs and also preconfigured for

the intended application use

Finally one thing that should not be

flexible in next-generation SSCs is the

user interface including the physical

dimensions pin or pad locations andsoftware user interface The product

family exemplified in figure 1 has a

standardized footprint pinout and

software user interface to minimize the

costs time and resources associated with

board layout calibration and climbing

the learning curve






The human heartbeat is arguably the single most important(ldquolife-and-deathrdquo) diagnostic indicator Thus electrocardiograms(ECGs) are one of the most significant diagnostic methods in that

they monitor heart function ECGs are not only used in a clinical settingbut are increasingly seen in personal health devices TraditionallyECG measurement conductive electrodes have been applied which aredirectly attached to the skin With the help of contact gel (wet or solid)to ensure that there is good electrical contact between the skin andthe sensor direct resistive contact is made with the patient Howeverconventional electrodes possess various disadvantages which arenot conducive for long-term use in non-clinical settings In addition tobeing potentially messy metal allergies can cause skin irritations andas a single-use item they are quite expensive

Non- co ntact ECG measurement using EPIC Sensors Measuring electrocardiogram (ECG) signals without skin contact is nowpossible using novel Electric Potential Integrated Circuit (EPIC) sensors

By Alan Lowne CEO of Saelig Co Inc




Non-contact measurement of

electrophysiological signals is of great

interest in healthcare settings with the

potential of reducing disposable costs

speeding up or simplifying measurement

techniques Monitoring long-term medical

conditions within the home or observing pilots

drivers soldiers and others in safety critical

situations is now possible without needing

skin contact Monitoring vehicle drivers for

health and alertness by detecting heart rate

and respiration or determining car occupancy

to adjust the ride handling and air bag

deployment with the varying size and location

of occupants is a vast potential market

Capacitive (insulated) electrodes can register

ECG signals without conductive contact to the

bodyndasheven through clothesndashand represent

an attractive alternative for a wide range of

new applications EPIC (Electric Potential

Integrated Circuit) is a completely new sensor

technology resulting from research at the

University of Sussex (UK) Novel ultra high

impedance EPIC sensors measure electric field

changes without requiring physical or resistive

contact This award winning patent-protected

sensor can rapidly measure electric potential

sources such as electrophysiological signals

or even spatial electric fields It therefore

has the ability to measure ECGs without

direct skin contact By adjusting the DSP and

amplification circuitry the sensors can be

tuned for detection at a distance as requiredfor differing automotive applications EPIC

sensor electrodes can be easily and discretely

incorporated inside car seat backs to acquire

the necessary biometric data

Signals measured on the human body always

include a large amount of noise the major

component of this being 50 or 60 Hz power

line noise capacitively-coupled to the body

from the surrounding electricity supply

Measurements such as ECG depend on being

able to extract the small electrophysiological

signals from the much larger noise signals

EPIC sensors can be used in ldquocontact moderdquo for

ECG measurement where the subject touches

both the capacitive electrode surface and

some metal at the system ground directly with

the skin This ground reference allows filtering

and differential amplification of signals from

two sensors to be effective in removing the

mains frequency noise leaving a high quality

ECG signal In non-contact ECG measurement

there is ndash by definition - no skin contact

and thus no direct connection can be made

between the subjectrsquos body and the system

ground Some other method of reducing

the power line noise is therefore required to

enable the ECG signal to be extracted reliably

and accurately One such method utilizes an

approach very similar to the ldquoDriven Right Legrdquo

(DRL) system that is used for the same purpose

in conventional ECG measurement techniques

In conventional ECG the DRL signal is coupled

directly to the patientrsquos skin The DRL signal

reduces power line noise on the sensor signals

by feeding back an inverted average of the

signals from two sensors on to the patientrsquos

body In non-contact ECG the generated DRL

signal can be capacitively-coupled to the body

through clothing via a piece of conductive

material placed ndash for instance ndash on the seat

or back of a chair Capacitive coupling of DRLsignals is described by Lim et al1 and Lee et al2

SYSTEM DESIGN

An ECG system can therefore be built into a

chair a mattress or clothing for instance The

DRL circuit improves the sensor signalnoise

ratio enormously In the example in Figure 1

EPIC sensors are mounted on a chair back such

that the electrodes touch the clothing on the

subjectrsquos back when resting normally against

the back of the chair The generated DRL signal

is connected to a piece of conductive material

placed either on the seat of the chair or at

the bottom of the chair back contacting the

subjectrsquos clothing in the normal sitting position

Copper-coated nylon fabric is one possible

material suitable for the DRL coupling material

but other conductive materials may be equally

successful A thin non- conductive material

such as a cotton fabric may be used to cover

both the sensors and the DRL coupling fabric if

required for instance when building the sensors

into a seat Consideration must be given as

to how material will reduce the coupling

capacitance between the sensor and the

subject or add additional noise to the signals

through static charging effectsFigure 2 shows the design of the DRL circuit It

is a standard summing amplifier generating an

amplified and inverted signal that is the average

of the individual signals A and B

The optimum value for Rf will be dependent

on the type of sensors being used as well as

the clothing being worn by the subject being

measured It should be set to achieve maximum

noise reduction while ensuring circuit stability

A value of 27kohms is suggested as a suitable

starting point for EPIC sensors

sensors and the DRL circuit into saturation

Because the system contains some large

impedances and hence has some very long

RC time constants settling times of tens of

seconds can be needed before a clean ECG

signal is seen During this period the signal can

either appear very noisy or be virtually flat

depending on whether one or both sensors or

the DRL circuit are ldquorailingrdquo The subject should

sit still during this time and wait for the circuit

to settle since continually adjusting position

will only make matters worse Settling timescan sometimes be reduced by turning off the

power to the demo box for a few seconds

CLOTHING

Good results can be obtained with one or two

layers of cotton material between the sensors

and the skin Other materials including a wool-

mix sweater and a polyester fleece in addition

to two layers of cotton material have been

successful Examples are shown in Figures 6

and 7 If the key greatest interest is in the ldquoR-Rrdquo

interval adjusting filter settings to reduce

or re-center the signal bandwidth can give

improved signal quality

STATIC

Because there is no direct physical contact

between the subject and any grounding point

there is no path for any static build up to be

discharged Under most circumstances staticbuild-up does not present a problem but

depending on factors including clothing

footwear flooring humidity levels in the air

and so forth static build up can sometimes

prevent the cardiac signal from being seen

clearly Product design must take into account

a discharge to the system ground to remove

the static charge

Rp the protection resistor is included to limitthe current that can be fed back to the human

body This resistor is essential in ensuring that

the subjectrsquos wellbeing is not endangered and

must not be omitted

IMPLEMENTATION

The demonstration of non-contact ECG is best

performed using an EPIC demonstration kit

Plessey part no PS25003 which includes the

necessary drive circuitry and switchable 50Hz

and 60Hz notch filters The inputs to the DRL

circuit can be taken from the BNC outputs

ldquoA amp Brdquo on the front of the demo box The

DRL circuit will require its own bipolar power

supply plusmn5V or plusmn6V is suggested A circuit

design including a battery power supply is

shown in Figure 3

Plesseyrsquos compact sensors (PS2520x) and disc

sensors (PS25101) provide equally good results

although for demonstration purposes disc

sensors are simplest to fix to a chair to make

contact with the occupantrsquos back Compact

sensors are recommended when designing a

custom-built system

EPIC sensors which are designed for contactelectrophysiology sensing give excellent

results in most cases Initial trials suggest that

custom modifications to the sensor design (eg

lower gain and higher input impedance) can

offer increased sensitivity and the ability to

detect weaker ECG signals

The shape of the measured ECG trace ndash in

terms of relative magnitudes of the P Q R S

and T waves ndash will depend on the positioning

of the sensors behind the subjectrsquos back If the

desire is only to measure the ldquoR-Rrdquo interval to

determine heart rate then the positioning of

the sensors is not critical Placing one sensor

either side of the spine separated by 6rdquo -10rdquo (15-

25 cm) at approximately the same height as

the heart is recommended as a starting point

For applications where signals from other

parts of the cardiac cycle are required the user

should refer to texts on bio-electronic signals

for guidance on sensor position

SETTLING TIME

When a subject first sits in the chair and leans

against the EPIC sensors the changes in

electric potential will normally send both the

ldquoMotion sensors are key components

in consumer devicesrdquo says Ben Lee

president and CEO of mCube The need

for smaller more powerful sensors

has emerged from the rise in mobile

applications such as gaming devices

tablets sports equipment and wearable

technology This wave of new applications

is a part of the Internet of Moving

Things (IoMT) which depends on high-

functioning sensors like accelerometers

gyroscopes and magnetometers to

deliver dynamic performance specs

for these moving devices mCube has

developed microelectromechanicalsystem (MEMS) sensors with significant

size reductions that allow for simplified

integration and implementation in

new IoMT applications

To achieve MEMS integration with

electronics mCube developed a

monolithic single-chip structural design

that is integrated with an application-

specific integrated circuit (ASIC) ldquomCube

is the first companyrdquo tells Lee ldquoto

successfully bring to market an integrated

MEMS+ASIC in high volume productionrdquo

Whereas traditional MEMS devices

occupied a larger area with lower yields

mCubersquos MEMS is fabricated directly on

top of the complementary metal-oxide

semiconductor allowing for unparalleled

integration and performance This is

achieved by bonding a single crystalsilicon wafer to the surface of a CMOS

plate A cap is then bon ded over the

MEMS structures at the wafer level and

is protected in a hermetic environment

With this unique process mCube is able

to overcome traditional drawbacks of

integrating MEMS due to the fact that

it is entirely monolithic meaning the

alignment tolerance between MEMS and

CMOS in mCubersquos accelerometer is 01 μm

as opposed to traditional distances of 3

to 5 μm As consumer needs are driving

rapid size reductions in the IoMT market

mCube positions itself ahead of the curve

by enabling integrated powerful and

seemingly invisible sensor technology

Just how small is m Cubersquos solution

Maximum size reduction is achieved byohmically connecting the MEMS to the

underlying CMOS through 3 μm vias

mCubersquos integrated device has four times

fewer the number of connected bonds

which ends up significantly reducing the

surface area needed for implementation

and ultimately the cost

MEMS sensors with significant

size reductions that allow for

simplified integration in new

IoMT applicationsrdquo

Flexible SensorsCollect Vitals

By Alex Maddalena Contributing Writer

Electronics are becoming increasingly omnipresent in our

everyday lives Industry trends of reduced device sizes

seamless integration in our environments and wireless

connectivity are changing the way consumers interact withtechnology One of the upsides of ubiquitous technology is

the collection of data that was previously inaccessible An

example of this is wearable health monitorsmdashbracelets and

bands that collect vital health statistics to inform users of

trends in their everyday activity which could ultimately lead

to healthier lifestyle and activity choices However one of the

biggest burdens of these health monitors is their form factormdash

rigid electronics are not the most natural option for wearing

during physical activities

Technology




As a result MC10 a flexible device

developer based in Cambridge

Massachusettes is developing a

new kind of wearable device with UCB

a patient-centric biopharmaceutical

leader that will redefine ldquoformrdquo in ldquoform

factorrdquo The Biostamptrade a prototype from

MC10 is a flexible sensor that effortlessly

adheres to the body and is able to bend

stretch and flex along with the user The

device is as unobtrusive as a Band-Aid

that can link to any bluetooth-enabled

mobile device to deliver real-time data

on the bodyrsquos vital statisticsmdasheverything

from hydration levels and heart rate to

UV exposure and body temperature The

Biostamp will enable users to receive

real-time data about their health

MC10 was founded by Professor John

Rogers back in 2008 after years of

seminal research on flexible technology

at Bell Laboratories and UIUC (University

of Illinois UrbanandashChampaign) The goal

of the research was to develop ways of

implementing electronics everywhere

imaginable by breaking down the devicersquos

form factors Rogers and his colleagues

eventually developed a way to form

silicon on incredibly thin elastomers

while still maintaining its properties

MC10 is the culmination of this extensive

and groundbreaking research and is the

exclusive licensee of the patent portfolio

that Professor Rogers built up over the

years of research

The innovations in materials science

revolved around the deconstruction of

the base material silicon Rogersrsquo team

was first able to dramatically reduce the

thickness profile of the silicon down to a

nano scale The second innovation was

the development of discrete chiplets of

silicon which could then be distributed

onto arrays comprised of nanomaterials

In the case of the Biostamp the array

is then embedded onto flexible rubber

band-like material that still maintains

the silicon semiconductor characteristics

allowing for unprecedented uses

adhering to the human body and this

allows continuous monitoring

ldquoProfessor Rogers is very passionate

about the idea of being able to change

peoplersquos lives through electronicsrdquo

said head of market development

Nirav Sheth offering a summary of the

companyrsquos mission statement ldquoAt MC10

we are all about dissolving boundaries

between humans and electronicsrdquo

The Biostamprsquos functionality reflects

the central tenets of the company by

ldquoThe Biostamp device is as unobtrusive as a Band-Aid

and can link to any mobile device to deliver real-time

data on the bodyrsquos vital statisticsrdquo

ldquoWe never looked at MC10

as a purely consumer

collecting data that will ultimately

help users make important decisions

about aspects of their health In fact

the device is undergoing crucial patient

testing to determine the efficacy of the

data it yields and whether it can provide

concrete claims on the health of the

user ldquoWe never looked at MC10 as a

purely consumer technology companyrdquo

Sheth claimed ldquoIt is also a medical

health companyrdquo

Considering themselves a medical health

company poses a unique challenge to

the MC10 team because the market for

ubiquitous technology like the Biostamp

does not fully exist yet However this

does not deter MC10 from continuing

development of the device on all frontsmdash

from material sciences research to

software and hardware development In

fact the company has been building its

team by bringing on board app developers

with cloud computing and algorithm

development expertise to help support

MC10rsquos devices in the back end ldquoThe

software aspects may be in the long

term the most differentiating aspects of

the technologyrdquo Sheth stated explaining

the companyrsquos software-related

investment Conversely the hardware
