Abstract In this paper the mathematical modelling and analysis of single beam piezoelectric energy harvesting is investigated using unimorph piezoelectric energy harvester to harvest wideband mechanical energy. The mathematical modelling is derived based on Euler-Bernoulli beam theory. Finally, the computed natural frequencies with voltage are presented in the form of dispersion curves. This type of study is important in green technology; especially in Energy scavenging, Renewable energy technology and Micro Electromechanical Devices (MEMS). Introduction: Energy harvesting technology is the process of converting ambient energy surrounding a system into useful electrical energy through the use of a specific material or transducer. Energy harvesting technology has the ability to create autonomous, self-powered electronic systems that do not rely on battery power for their operation. A widely studied form of energy harvesting involves the conversion of mechanical vibration energy into electrical energy using piezoelectric materials, which exhibit electromechanical coupling between the electrical and mechanical domains.
