This paper offers layout design and simulation of a piezoelectric cantilever beam for electricity harvesting the use of mechanical ambient vibration converted by mean of piezoelectric effect. On this paper designed structure optimum power output in the distinctive piezoelectric substances in a bimorph cantilever beam configuration. The microstructure of the beam was designed by way of using COMSOL 5.1. The Lead zirconate titanate (PZT-5A) and Structural Steel materials used for active bimorph layers of size 21×0.14mm and 21×0.16mm respectively. The cantilever structure Generates maximum power of 1mw and generated voltage of 5.39V turned into received from the harvester at 12kΩ resistive load with the acceleration of 1 g (g = 9.81 m/s2) at resonant frequency of 75.5 Hz. This power harvester can be used for numerous purpose inside the area of MEMS sensors and Wi-Fi sensor networks.read more
