Parallel Pre-stressed Piezo Actuators

Piezo ActuatorsOverviewParallel pre-stressed piezo actuators (PPA) are preloaded low voltage piezoelectric actuators using a direct-acting multilayer ceramic stack (MLA). Most conventional Direct Piezo Actuators use an MLA preloaded by Belville washers on the end of...

Amplified Piezoelectric Actuators (APA®)


APA120 actuator and driver evaluation kit and paperclipPatented by CEDRAT TECHNOLOGIES, amplified piezoelectric actuators are a mechanical magnified preloaded stack of low voltage piezoelectric ceramics (MLA).

The mechanical amplification is obtained thanks to an external elliptical shell made of stainless steel which magnifies along the short axis the MLA deformation occurring along the main axis. This elliptical frame also protects the MLA against tensile force. It provides the user with mechanical interfaces for easy integration. This prestressing and magnifying flextensionnal frame applies an optimal preloading force to the MLA which ensures a longer life time and better performances than traditional mechanical amplifiers based on lever arm and flexure pivot, when dynamically applied.

The APA® developed by CEDRAT TECHNOLOGIES has force and displacement performance ranges exceeding those of direct or bimorph Piezo actuators.

10 series (uXS, XXS, XS, S, SM, M, MML, ML, L, XL) of APA® are available in order to meet the different needs in terms of stroke, force and dimensions.
