Electroactive polymer EAP actuators made with PolyK piezoelectric PVDF.
Film thickness of 40 um, operation voltage up to 2000 V.
Each actuator active area is 10 mm x 35 mm, with 40 um passive layer. Two thin copper wires for connecting to external high voltage power supply or amplifiers. The plastic box is NOT included.
Other size or active film thickness can be produced in one week.
Used in soft robotics, haptics actuators, loudspeakers, energy harvesting, piezo sensors, etc.
A recent project from UC Berkeley and Tsinghua University used PolyK PVDF EAP actuator for soft robotics:
