Powerful tubular core free dielectric electro activate polymer (DEAP) push actuator

Abstract

DEAP Actuator structures are being developed and optimized with focus on high volume automated manufacturing echniques and processes. New core-free and self-supporting structures are capable of providing PUSH forces without external mechanical tension mechanisms or film pre-strain. Fundamental actuator design and construction principles are presented. A simple quasi-static model governing behaviour is presented and actual results from this new class of push actuator devices are compared to modelled behaviour. These actuators have the capability of modest stroke and high actuation forces. Actuators can be easily scaled to fit the application based upon physical size and force-stroke relationship. © 2009 SPIE.
