CEDRAT Piezoelectric Actuators & Electronics Devices

CEDRAT Piezoelectric Technologies 

Micromechatronics, Inc. distributes CEDRAT piezoelectric technology. CEDRAT offers a wide range of standard piezoelectric actuators having the following outstanding characteristics: high force and large displacement in compact sizes, high resolution within the nanometre range, very short response time below 1 ms, life time greater than 10^10 cycles, low voltage supply below 150V DC, no backlash and no play, low power consumption when static, severe environment compatibility (vacuum, cryogenic, high temp,...).

In order to meet varying customer actuation specifications, the CEDRAT Group has developped 3 different families of standard piezoelectric actuators with their corresponding drivers and controllers:

Amplified Piezo Actuators (APA) 

Have been designed in order to offer the largest possible stroke while keeping a resonable size and a long lifetime.

Parallel Pre-stressed Actuators (PPA)

Use expansion of the active material, in 33-mode, for producing a useful displacement.  Since pre-stress level is better controlled, they display an improved performance behavior than a DPA, and can be operated at resonance.  The displacement is directly proportional to the voltage. 

Piezo Actuator' Mechanisms 

Starting with standard piezo actuators, several mechanism have been designed to assist in controlling several degrees of freedom. 

Drivers & Controllers  

Amplifiers and controller systems specially designed to drive CEDRAT piezoelectric technology.
