This work main objective is to compare the performance of the Vertical L-shaped Piezoelectric Energy Harvester (VLEH) against Horizontal Orthogonal Piezoelectric Energy Harvester (OPEH). VLEH is a continuation project of OPEH where the piezoelectric position is changed from a horizontal orientation to a vertical manner. In this project, the piezoelectric material is applied by a mechanical stress via vibration and in return it produced an electrical energy. Succession of this project to produced a high open circuit voltage could be a contribution towards supporting the renewable energy industry. The application of the energy harvester is to power up wireless sensor nodes and as well can be placed in a remote area where electricity is a precious commodity. The VLEH piezoelectric were attached and tested with four different types of extension arm material and at five different extension arm length with a range frequency of 10-90 Hz.
