CEDRAT TECHNOLOGIES has developed a range of reliable piezoelectric products for high bandwidth
& precise motion: APATM and PPA actuators as well as various precision mechanisms with driving and
control electronics. Applications include environmental testing of materials and electronic devices,
vibrations and fatigue tests, micro nano positioning, micro scanning, laser cavity tuning, optic fibber
stretching, vibration generation, vibration control (active damping, isolation), fast machining, mirror tilting,
flap control, fluid control (metering valve, injection)…
CEDRAT TECHNOLOGIES is developing a new range of sensors and detection system solution, based
on magnetic or piezoelectric technologies
Sensors and detection systems
> Low cost eddy current sensors and conditioner: In a context of always smaller and smarter mechatronic devices, the need of more integrated sensors
becomes critical. Particularly, small mechanisms using small actuators like piezo actuators require
compact sensors, with performances that measure up to the actuators characteristics. Eddy current
sensors are widely used for non contact position,
displacement, and proximity measurement with very
good performances (bandwidth resolution, linearity,
robustness in dirt environment). CEDRAT
TECHNOLOGIES propose solutions based on
probes made on multilayer printed circuit.
Customized realisation and design are available.

> CTS, new kind of contact less torque sensor, and even more: To overcome traditional limitations of torque sensor,
and provide in the same time, in one sensor, the
torque, the speed and the position, CEDRAT
TECHNOLOGIES has developed a new sensor named
CTS.
Reliable, easy integration on existing or new design, the CTS is dedicated to simplify engineering for the
development of mechatronic systems. This torque sensor is contact less, compatible with severe
environments, reliable, compatible with every shaft materials. It works on the measure of the shaft
torsion and is the fruit of CEDRAT TECHNOLOGIES skill in small displacement and mechanical
amplification. Optional measures such as speed and position can be integrated directly within the CTS.
Not an off he shelf product, the CTS is adapted to be compatible with customers designs and
requirements.
> Ultrasonic based structural health monitoring Ultrasonic-based SHM (Structural Health Monitoring)
applications commonly rely on the use of piezo-electrical
patches to emit and receive ultrasonic waves. Because of
the elevated number of echoes and possible modes of
propagation of the waves within the structure, those
applications suffer a burden of signal processing.
The reduction of the complexity of the SHM detection
schemes is based on selecting the mode and direction of
the Lamb waves received. The piezo-composite is
composed of a row of eight independent ceramic pillars separated with polymer, so it is a 1-D matrix of
independent piezo-patches. Used with adequate electronics and signal pre-processing, it was shown
that it allowed selecting direction and mode of the Lamb wave received.

Piezo actuators and piezo mechanisms, a solution for testing
> Parallel Prestress Actuators PPAs perform short strokes (0-200micron) and high forces (0-10kN).
These actuators are based on an external frame to prestress the piezo
Ceramics and to provide metal interfaces. Special hollow versions,
called HPPA have been developed for laser cavity tuning in Lidars.
APATM& PPA
> Amplified Piezo Actuators APATM perform medium strokes (0-1mm) and high forces (0-10kN). These actuators are based on a
shell to prestress the piezo ceramics, to amplify the piezoceramic stroke and to provide metal interfaces.
The shell also protects the piezo ceramic and renders the actuator insensitive to off-axis forces. Thanks
to the amplification, the actuator axial deformation can reach almost 10%. For example the APA 900M
can provide a stroke of 800µm in a height of only 10mm. Efficiency of the amplification has been
optimised to keep useful force and stiffness.
Because of their structure and their prestress, these PPA and APATM actuators can bear large stresses.
Thus, they can be used in dynamic applications offering a large lifetime (>1010 cycles). This is beneficial
in micro-scanners, fast shutters, fast tunning, piezo motors, machining …They can also be operated at
resonance for sonic and ultrasonic vibrations generation, as for glass cutting.

At last they can bear high external vibrations. It is why they have been adopted in a lot of embedded
applications, such as space telescopes and microscopes, military IR cameras (brand names include
NASA, ESA, THALES …).
The other advantages of APATM and PPAs are high force, rather large displacements, with nanometre
resolution. These actuators, especially the APATM can be scaled to the applications. Toward
miniaturisation, micro actuators APA 150XXS offer a stroke of 0.15mm and a force of 6N with a mass of
about 1gr. Toward very large actuators, an APA 500XXL of 0.5mm stroke and 10kN force has been
realised for ESO ELT telescope. A large series of actuators
cover all intermediate size, with various stroke up to 1mm and
forces. Optionally, PPAs and APATM are cryogenic, non-magnetic,
vacuum compatible, mechanically damped for reducing effects of
vibrations, strain-gages equipped.
Piezo actuators & electronic devices
APATM and PPAs have a very strong heritage
from air, space and military fields but CEDRAT TECHNOLOGIES industrialisation efforts have made
them cost-effective.
> Various mechanisms have been (or can be) developed using these APATM and PPA
components:
X, XY and XYZ stages are APATM - based X, XY and XYZ
mechanisms offering guided motion of 20 to 400 microns.
X and XY stages are thermally compensated. They
can be controlled by strain gages or by Eddy Current Sensors
for close loop operations. The OPDA is a special X stage
developed for Oerlikon Contraves for LISA space mission. XY 25XS Stage
TT and DTT mechanisms are APATM - based single or double tilt mechanisms of up to 10 mrad
rotations, which can be combined with XY and XYZ stages.
OPP is an Objective Piezo Positionner for refocusing functions in optic microscopes; The guided z-
stroke is 140micron.

stroke. This new technology receives a MICRONORA2008 Golden Micron Award. Although all APATM
can be used to realise SPA motors, the trend is to expand the range of products toward micro motors.

CEDRAT TECHNOLOGIES has developed several classes of low-voltage Piezo Actuators to cover a
wide range of needs and application. APATM are solid-state long stroke linear actuators. They are based
on the expansion of the active material and on a mechanism for amplifying the displacement. APATM
offer high displacements combined with large forces and compact size along the active axis.
Piezo evaluation pack : APA 120S & CAµ10 amplifier
The evaluation pack aims at an easy evaluation of the
CEDRAT TECHNOLOGIES’offer in static conditions.
It includes:
• An amplified actuator APA120S
• A linear amplifier CAµ10
• Connectors APA 120S/CAµ10/Connectors
The actuator APA120S can bear load up to 0.5 kg over 140µm and in a compact size.Is the highest
stroke and lowest force version of the Amplified Piezo Actuator S series.
The CAµ10 can deliver a voltage up to 150V and has 2 channels.
It is a unipolar (5V..150V) miniature linear amplifier with low noise and low cost features. A SPI digital to
analogue converter is able to convert 12 bits words in analogue signal for the linear amplifier. Optional
inputs can be connected if necessary to shunt the SPI bus and send directly the analogue order on the
linear amplifiers. The CAµ10 is compatible with the numeric controller UC45.
The main features enlightened by the evaluation pack are: • A high stiffness of the actuator
• A nanometer resolution
• A good repeatability
• An excellent reliability

Stepping Piezo Actuator
This new technology has received a MICRONORA 2008 Golden Micron Award. SPAs are new linear Stepping Piezo Motors for stroke up to 20mm with blocking at rest, benefiting of the
APATM heritage. They can perform this long stroke by accumulation of small controllable steps. Using
additional fine mode, they also offer a positioning capabilities of less than 1 nm along the 20mm stroke.
Between each step the actuator is locked in position. When the long stroke is performed, it can be also
operated in a deformation mode for a fine adjustment. In this case, the stroke is proportional to the
applied voltage, which leads to a nanometer resolution and a high bandwidth.
This actuator can be supplied with CEDRAT TECHNOLOGIES standard Linear Amplifiers.
SPAs offer:
- A blocking at rest in any position (locking without power supply),
high stiffness,
- A nano positioning resolution all along the stroke
- Non magnetic behavior
