This paper discusses the design and simulation of cantilever beams for mechanical vibration power. On this paper an optimal power output is configured in a biomorphic cantilever beam configuration for the single piezoelectric substances. The structure of the beam modeled in COMSOL 5.1. The LZT (PZT-5A) material used and the size taken as 21x0.14mm in case of active bimorph layers and in case of structural steel the size taken as 21x0.16mm. This cantilever structure produces a max. power of 1mw, and 5.39V at a resistive load of 12k at resonating frequency of 75.5 Hz with an acceleration of 1 g (g = 9.81 m /s2). In the area of the MEMS sensors and WiFi networks, this power harvesting machine can be used for many purposes.
