Flexible Design

Easy to produce

Disadvantages

Total Energy Content

Power Capability

Lifetime

flat, thin, flexible, large-area

best suited for printed SmartObjects

New layout

New screens

You need:

Substrates, Inks and a Machine

Michael Faraday

Gorg Simon Ohm



Electrochemical Systems A Roadmap

History and Future

At the end Lithium is what counts

The cheap Work Horse: Zinc-Carbon

Zinc-Carbon goes rechargeable



Nickel – Metal hydride

FLEXIBILITY

Duration: 01.06.2011 – 31.05.2015

Task: DC power supply for different

Smart Objects (Organic Electronics)

Topic: Flexible Multipurpose Bendable

Integrated Light-Weight Ultra-Thin Systems

A serial connection up

to 24V is possible

But environmental

concerns

Layout successful But Pick-and-Place?



Lithium - Ion

BASMATI

• Fully printed

(except of the separator)

• Current collectors

hot embossed R2R

• Lamination with

office laminator

• First working samples



Printed rechargeable

Zinc-Air cells

Samples to be investigated



Zinc - Carbon

The Principle

• How does Zinc Carbon works

The system is very old:

Advantage:

Near-Neutral-Electrolyte NNE is easy to print

No reactions with the atmoshere

Cheap and environmental friendly



Zinc - Carbon

The Design Variantes• The performance data decide

• Co-planar

Advantage Disadvantage

thinner object increasing

higher flexibility internal resistance

• Stacked

Advantage Disadvantage

large area low flexibility

high rate capability



Zinc - Carbon

The INNPAPER project

Innovative and Smart Printed Electronics based on Multifunctionalized Paper:

from Smart Labelling to Point of Care Bioplatforms

• Self-powered multiplexing disposable smart-labels

• Paper-based PoC quantitative immunoassays,

• Self-powered PoC genetic assays

TECHNOLOGIES



Printed Batteries

IOT

Things get intelligent

At this time we don't know which things are concerned -

But every IOT device needs

sensoric and

electronic and

energy for commuication



Printed Batteries

Our samples

already existing

Different datalogger for temperature and humidity

Printable circuits touch switches on different substates

Printed antennas

Printed heatings

Printed and wireless lamps



Monitoring storing and communicating

Seamless cool chain and humidity

monitoring for food, pharmaceutical

and industrial products.

UV, shake,

The logger is inside or outside of the

package.

With the neftag-app is it possible to readout

the temperature curve anytime with the RFID / NFC antenna.

Small flat and flexible.More than 20000 readings

are stored. Interval is free adjustable by the user.



Low temperature soldering

• Soldering on printed silver circuit path

is not possible because the curcuit

dissolves into the soldering point

A kind of barrier layer is needed to avoid

dissolving

Elmeric has developed a low-temperature-

process, whereby soldering on printed

silver circuits is possible

The low-temperature-process allows to use

PET-Foils and many other materials.

Abb.1: Dissolving silver circuit

Abb.2: Good wetting soldering point with a barrier layer

Abb.3: cross sectionAbb.4: soldered component



Samples of IOT

User interfaces are moving onto the surface of the application

Electronic is printed without PCB board. The board is the surface.



3D parts with functional surfaces

Areas of printed touch switches are used in the automotive sector, in furniture surfaces, in medical technology and many more, wherever light, flat and easy-to-clean control panels are required.

The printed functionality is printed directly behind the design of the surface. These electrical conductive polymers are flexible and able to form into 3D parts.



Advantages of Printed Batteries

FlatnessPrinted with design or other functions like antenna, el. circuit, sensors …Adjustable to the application concerning both electrical and mechanical dimensions.Printable roll to roll on state of the art screen printing machines.



Samples of systems with batteries



Actual projects with printed batteries

Intelligent labels: The producer knows where his product is right now.Is it on the right way?Is the seal broken? Do I have to produce more? Does my customer use it or not?Is the product lifetime over when the seal is broken?…

Wearables: multifunctional clothes with removable / non removable, washable, printed batteries.

Medicine: Intelligent injection needles with sensors on the top.Stretchable printed batteries, biocompatible.
