Electroactive polymer EAP actuators and speakers made with PolyK piezoelectric PVDF.
Come with connectors, audio cable (to your smart phone or laptop) and to power supply, and a 9V battery powered driver (battery not included)
This pack includes one driver and two piezo EAP elements with connectors, one audio cable, and one power cable (from driver to piezo EAP element).
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.
The output changes with frequency.
100hz 1vpp-150vpp 3Vpp-250v
100khz 1vpp-50v vpp
Other size or active film thickness can be produced in one week.
Used in soft robotics, haptics actuators, loudspeakers, energy harvesting, piezo sensors, etc.
