Abstract

C-blocks are novel piezoelectric actuators that allow for a variety of different architectural configurations that will directly address application requirements without external leveraging. A very useful architecture is a series in which C-blocks are connected end-to-end. Serial architectures increase the deflection of the actuation system without impacting the force output. This paper presents the derivation of an theoretical model that accurately predicts the quasi-static force-deflection behavior of a generic C- block serial actuator configuration. This model is verified with five experimental case studies. In these case studies, the effects of changes in geometry, material, and configuration parameters were investigated using a variety of prototypes fabricated from polymeric and piezoceramic materials.
