Electroactive polymer EAP actuators made with PolyK piezoelectric PVDF.
Film thickness of 12 um, operation voltage up to 2000 V. Visible displacement even at 10 V.
Each actuator active area is 10 mm x 35 mm, with 40 um passive layer. With connectors and cables to your power supply.
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:
