  • Micromachined, piezoelectric vibration-induced energy harvesting device and its fabrication
    Patent number: 7687977
    Abstract: A micro-sized power source. A piezoelectric power generator, capable of harvesting energy from environmental vibration with lower level frequency, including a dielectric frame loosely containing a piezoelectric panel. The piezoelectric panel includes an electrode and a piezoelectric layer formed over an electrode and dielectric layer and an end mass formed on the piezoelectric layer. The end mass provides weight to cause the piezoelectric panel to move (vibrate) within the frame and causes the generation of electrical power.
