A Study of effect of tip mass density, orientation and resistance on vibration energy harvester

Abstract

Energy harvesting is extracting energy from ambient sources. Vibration energy harvesting area have received attention of many researchers to power wireless sensors and low-power electronic devices from smart materials. In this paper, effect of tip mass density, orientation and resistance on  cantilever beam bounded with piezoelectric patch is studied. The analytical equations of beam is derived using Euler Bernoulli beam assumptions, constitutive equations of piezoelectric material and Hamilton’s principle.
