摘要

All new cars in the US were required to include TPMS by 2007, and in 2022, the EU passed laws implementing similar requirements. The widespread utilization of batteries presents a serious environmental risk because of problems with waste and disposal. In order to address environmental issues related to battery-operated devices, this research focuses on the design of a sustainable energy solution for tire pressure monitoring systems (TPMS) in automobiles. This study presents a Piezoelectric Energy harvester (PEH) as an environmentally friendly substitute that can harvest energy from a tire’s mechanical deformations. The aluminum substrate is used as a structural support, and PZT-5 H is used as a piezoelectric material. PEH is designed to be mounted on the inner surface of the tire. Despite traditional methods that position energy harvesters on the rim, where deformations are low, the harvester directly harvests energy from the constant deformations induced by tire pressure and road contact, creating a more stable and higher energy production. Results indicate that output voltage increases as the car’s speed increases, reaching peak output at about 90 km/h. The power output also increases gradually with speed, demonstrating that, in addition to power TPMS, excess power can be stored. This innovative approach promises to minimize the environmental effects of automobile technology while simultaneously satisfying the energy requirements of TPMS.
