This project investigates the potential of harvesting kinetic energy from rumble strips using piezoelectric materials, which convert mechanical vibrations caused by vehicle movement into electrical energy. Rumble strips, when subjected to the force of passing vehicles, generate vibrations that can be captured by piezoelectric sensors embedded within the strips. The integration of advanced materials such as Elastollan 1190A (TPU) and Sorbothane 70 Duro significantly enhances the efficiency of this energy conversion. Elastollan 1190A, with its high mechanical strength and flexibility, is employed to encase the piezoelectric elements, providing protection while optimizing the transmission of vibrations. Sorbothane 70 Duro, known for its superior damping properties, further improves the system by reducing energy losses from excess vibration and enhancing the overall power output of the piezoelectric sensors.

By combining these materials, the project aims to create a more effective and durable energy harvesting system. Elastollan 1190A ensures that the piezoelectric components remain secure and functional under varying environmental conditions, while Sorbothane 70 Duro improves the energy conversion efficiency by absorbing unnecessary shock and vibration. This research focuses on optimizing the performance of kinetic energy harvesting systems, providing a sustainable method for converting waste energy into usable power. The outcome promises to contribute to energy-efficient technologies and the development of alternative energy sources, particularly for applications in transportation and road infrastructure.
