Experimental study on the effect of electrical and mechanical conditions on piezoelectric energy harvesting

Energy harvesting systems for low power consumption devices are increasingly required for different applications, such as autonomous sensors and Internet of Things. This work is about the evaluation of the electrical energy recovered by a ceramic piezoelectric disc, under different mechanical and electrical conditions. The vibration excitation of the disk is of different amplitudes and frequencies, the disk is fixed in different ways, while the recovery electric circuit is of different configurations.
