Abstract

We have proposed a Spontaneous Polarization Electret (SPE) consisting of ferroelectric to increase output power of electrostatic vibration energy harvesters. Lead zirconate titanate (PZT) ceramics were employed to develop the SPEs. For comparison, a conventional electret was also prepared by implanting charges into a 10-μm thick CYTOP® polymer by using point-to-grid corona discharging method. The maximum output powers obtained from a vertical-type capacitive energy harvester are 8.6 μW for the SPE and 5.1 μW for the CYTOP® polymer electret, at total load resistance 40.5 MΩ. The SPE demonstrated the higher potential compared to the conventional polymer electret.
