چکیده
In order to realize the collection of micro or small vibration energy, a micro-power generator based on two piezoelectric Macro Fiber Composite (MFC) films is proposed. The consists double MFCs type vibrator and displacement amplifying mechanism, which can achieve output high energy density. design process this kind presented. Based LabVIEW platform NI Data Acquisition (DAQ) card, voltage acquisition system built, power are collected calculated. Experimental results show that maximum 6.2 mW under transient excitation. Under continuous excitation with load resistance 10 k? an frequency 26 Hz, up 11.9 mW. research lay foundation for application proposed generator.

Micro piezoelectric vibration generator has a wide application in the field of microelectronics. Its natural frequency is unchanged after being manufactured. However, resonance cannot occur when the natural frequencies of a piezoelectric generator and the source of vibration frequency are not consistent. Output voltage of the piezoelectric generator will sharply decline. It cannot normally supp...

15 صفحه اولA piezoelectric micro generator worked at low frequency and high acceleration based on PZT and phosphor bronze bonding
Recently, piezoelectric energy harvesters (PEHs) have been paid a lot of attention by many researchers to convert mechanical energy into electrical and low level vibration. Currently, most of PEHs worked under high frequency and low level vibration. In this paper, we propose a micro cantilever generator based on the bonding of bulk PZT wafer and phosphor bronze, which is fabricated by MEMS tech...
