Abstract

This work investigates the shape optimization of piezoelectric energy harvesters subjected to mechanical vibration using ABAQUS/Standard software. Three piezoelectric energy harvesters with different dimensions but the same areas were created to identify if model dimensions have an impact on the output voltage. The models were tested at different speeds to create an output voltage. Once the output voltages were obtained, the results were compared with each other to find if shape optimization on piezoelectric energy harvesters has an impact on scavenging energy from mechanical vibrations.
