Energy harvesting system for intelligent tyre sensors
An intelligent tyre system enables the active chassis control system to directly access the information about tyre road interactions. However, supplying power to the system is still a bottleneck which limits the applicability of the intelligent tyre system. This paper proposes a piezoelectric energy harvesting system with energy storage to address this issue. The system was installed to the inside of a car tyre and measured with a chassis dynamometer. The harvester was found to produce approximately 88 mW of power at a driving speed of 60 km/h, which is enough to supply energy for a low power in tyre sensor system with radio link connectivity such as a tyre pressure monitoring system.
