Efficient Road Surface Thermal Gradient Conversion into Electricity

The major requirement for clean and sustainable energy has led researchers to explore alternative sources that can be built into everyday infrastructure. Roads, which constantly absorb heat from sunlight and experience vibrations from moving vehicles, provide a promising opportunity for energy harvesting. In this project, a combined method is proposed where both thermoelectric and piezoelectric systems are used to generate power. The thermoelectric modules are use to make the tem- perature difference between the road surface and the ground, while the piezoelectric components is used to capture mechanical energy from vehicle-induced vibrations.The harvested energy form the dual process is used for the purpose of the real-time applications such as self-sustained sensors, roadway lighting, and smart traffic infrastructure.It also improves the efficiency of electricalenergy. The integrated system is eco-friendly,reliable and low-maintenance.
