Amplified Piezoelectric Actuators

Patented by the CEDRAT Group, the Amplified piezoelectric actuators, is 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 the CEDRAT Group has force and displacement performance ranges exceeding those of direct or bimorph Piezoactuators.

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:
