This paper presents an overview of the widely usedconventional linear actuator technologies and existing electroactivepolymer based linear and rotary actuators. It also providesthe conceptual, control and driver design considerations for anew dielectric electro-active polymer (DEAP) based incrementalactuator. The DEAP incremental actuator consists of threeindependent DEAP actuators with a unique cylindrical designthat potentially simplifies mass production and scalabilitycompared to existing DEAP actuators. To accomplish theincremental motion, a high voltage (HV) bidirectional DC-DCconverter, independently charges and discharges each capacitiveDEAP actuator. The...
