Piezoelectric cantilever as a resonant structure can be used both as sensor as well as energy harvester and hence can be integrated as a self-powered system. When excited at a frequency near to its resonant, maximum electrical power is generated, therefore it functions as a micro-power generator. When excited to a frequency which is far from the range of the resonant, the voltage signal generated...
This paper demonstrates the operation of a self-power vibration measurement system. A piezoelectric material in the form of a cantilever is being used as a generator which harvest energy from ambient vibration source and transform into useful electrical output. The vibration sources is measured with a MEMS based accelerometer, which is powered up by the transformation of electrical energy derived...
