background

● Ceramic piezoelectric materials (such as PZT), mechanical strength is fragile.
● Polymer piezoelectric materials are flexible and durable, but output impedance is high.
● High voltage polarization is required in case of polymer piezoelectric materials.

summary

● Making thin membrane by spin coating of polymer.  
● Making electrode by ink jet printer.
● Poling process is not needed.

predominance

● Manufacturing facility cost is low.
● Enable to apply on various materials.
● Power up by stacking structure is possible.

application/development

● Vibration or wind-generated electric power. 
● Wearable power generator.
● New type sensor.
