Vibration-based Piezoelectric Energy harvesters convert ambient vibration energy into an applicable electrical charge for wireless sensors, IoT applications, and charging the battery, which is most important to range improvement of the Electric Vehicle. This study analyses different beam configurations from Industrial machines, such as simple, Tapered, L-shape, and U-shape Cantilever configurations with Proof mass. Nonpiezoelectric to piezoelectric ratio is taken as more than unity and formulated linear dynamics equation of the entire structure for unimorph beam. The electromechanical Coupling behavior of such configuration with respect to important performance parameters is analytically evaluated and validated with COMSOL Multiphysics simulation. After analysis of the beam configuration, it is found that a U-shape unimorph Cantilever can generate a maximum power of 23.5 mW and a maximum Voltage of 23.6 V among all Configurations. Using this work, researchers can optimize and design performance energy harvesters for various industrial applications or the role of COMSOL multiphysics for energy harvesting.
