Smart Lane for Cars using Piezoelectric Devices

As the evolution of modern cars has been increased day by day the cost of fuel consumption also increases manifold. Nowadays the usage of batteries has been utilized in electrical vehicles. The problem in using electrical vehicles is that the batteries have a limited power backup and hence cannot be used for longer trips. To fulfill these requirements and considering the vision of automation in the production of fuelless cars, the reliability of the cars can be increased with the help of piezoelectric devices. Piezoelectric effect or piezoelectricity is defined as, generating an AC voltage when a material is put into mechanical stress or when a material undergoes a vibration. In this research work, two system models are designed and compared. The models are multi-array piezo systems (MAHS) and the proposed hybrid piezo harvesting system (PHS). The maximum efficiency obtained in MAHS is 58.35% and the PHS maximum is 82.69% Approximately the high-pressure voltage generation is improved by 24.34% The lower efficiency is 17.69% and 12.43 % for PHS & MAHS respectively. This system provides better energy conversion efficiency for energy harvesting systems in real-time scenarios, especially generating power from the traffic lane.
