More Information
Summary:A piezoelectric energy harvesting device (PEHD) comprising a driving element, conducting element, piezoelectric layer and non-piezoelectric layer capable of converting ambient mechanical energy into electrical energy. The piezoelectric layer may be constructed from PMN-PT or PZT having a thickness of about 1-150 μm. The PEHD may be used to generate about 1 W. The harvested energy may be stored and used to power microelectronic devices and rechargeable battery technologies.
