A major challenge that arises with the broad use of wireless smart sensor networks is the provision of energy for these wireless sensors over extended periods of time. Energy harvesting is a rapidly expanding industry, and researchers and developers are making steady progress in optimizing power output from existing sources. Solar, wind, thermal, vibrational, and other forms of energy are only some of the ad hoc options that may be found in nature. In comparison to the other approaches, energy harvesting using vibrational energy sources stands out for its independence from external factors and its universal availability. Due to its great effectiveness in converting ambient vibration into usable energy and its relatively simple design, piezoelectric energy harvesters have become the subject of much study. Here, we propose utilizing COMSOL Multiphysics Software to build, simulate, and analyze a micro-cantilever array-based piezoelectric energy harvester. An array of cantilevers of varying lengths is created to harvest energy from a broad spectrum of vibrational force. Using EB beam theory, the ideal proportions of length to breadth and length to depth are determined. The suggested energy harvester can produce a maximum voltage of 0.6 V with a resistive load of 1000\ \Omega and an input acceleration of 1; this may be adjusted for our specific areas of study and practical applications. Collectively, a huge array of these cantilever beams might provide a higher voltage that could be utilized to power smart electronic devices.
