energy harvesting from surrounding environment has been attractive for many researchers in recent years. therefore, developing appropriate test apparatus to study energy harvesting mechanisms and their performance is of paramount importance. due to their electromechanical characteristics, piezoelectric materials are used for harvesting energy from environmental vibrations. for optimum utilizati...

In this paper, we present mathematical analyses to consider the effect of material properties on the sensitivity of the Microelectromechanical systems (MEMS) piezoelectric hydrophone and improve the sensitivity by choosing the proper material. The selected structure in the present paper is a piezoelectric hydrophone able to work at low frequencies. The piezoelectric hydrophones are widely used ...
