CEDRAT APA^® Overview

CEDRAT Piezoelectric Technologies

Patented by CEDRAT TECHNOLOGIES, the Amplified Piezo Actuator (APA^®) is a mechanical magnified preloaded stack of low voltage multilayer 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 flextensional 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. APAs have force and displacement performance ranges exceeding those of direct or bimorph Piezoactuators. Ten series (uXS, XXS, XS, S, SM, M, MML, ML, L, XL) of APAs are available in order to meet the different needs in terms of stroke, force and dimensions:
