Fundamental Study Of Energy Harvesting Using Piezo-Electric Device On The Road

Sustainable power generation may be achieved in converting ambient energy into electrical energy. Some possible ambient energy sources are, for instance, thermal energy, light energy or mechanical energy. The focus here is on the transformation of mechanical vibrations, existing almost everywhere. In this field, electromagnetic and electrostatic generators have been developed. However, the piezoelectric generators are of major interest due to their solid state nature facilitating their integration. That's why different approaches of energy harvesting using piezoelectric materials have been developed over the past few years. Optimization of Piezoelectric Electrical Generators (PEG) is an essential stage to consider their miniaturization while preserving a significant output power level.
