Abstract:

The automotive industry explores to power wireless sensor nodes for sensing and data communications through energy harvesting from automobiles. Vibration and thermal gradient is present for a vehicle in operation, vibration and thermal energy harvesting using piezoelectric and thermoelectric generators is feasible for vehicles. This seminar presents multi-source energy harvesting followed by vibration and thermal energy harvesting in the automobile environment. It discusses an energy harvesting circuit to extract maximum power, while minimizing the power dissipation. It presents experimental results on the power harvested from vibration and thermal gradient in an automobile environment and shows a wireless sensor node powered by the energy harvesting circuit.
