Powerful tubular core free dielectric electro activate polymer (DEAP) push actuator
2009
DEAP Actuator structures are being developed and optimized with focus on high volume automated manufacturing
techniques 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.
