Patent number: 7698926Abstract: An energy harvesting system and method. An array of cantilevers with PZT films is electrically connected to an energy harvesting device that converts vibration energy to electrical energy. An AC output signal provided by the cantilevers can be rectified to a DC output, thereby avoiding impairment in total electrical output. The DC output terminals can be connected in parallel and/or in series in order to achieve a higher voltage and/or a higher current that prevents the output from different cantilevers from counteracting one another. The connection circuitry includes one or more rectifying components integrated with one or more micro-cantilevers into a single integrated circuit chip. An oscillograph can be utilized to monitor the DC output voltage signal from an associated testing circuit.Type: GrantFiled: April 26, 2007Date of Patent: April 20, 2010Assignee: Honeywell International Inc.Inventors: Xinhui Mao, HuaBin Fang
