| 摘要 |
A piezoelectric energy harvesting device (PEHD) comprising a driving elem ent, conducting element, piezoelectric layer and non-piezoelectric layer cap able of converting ambient mechanical energy into electrical energy. The pie zoelectric layer may be constructed from PMN-PT or PZT having a thickness of about 1-150 ?m. The PEHD may be used to generate about 1 W. The harvested e nergy may be stored and used to power microelectronic devices and rechargeab le battery technologies.
