This paper presents a novel type of triboelectric-based self-powered sensorfor tire condition monitoring. The triboelectric based sensor is made of highlyflexible, mechanically and thermally durable, and cost-effective polymericmaterials. The authors firstly report the location inside of a tire for attachingthe sensor to monitor tire conditions. Then, the authors analyze theperformance of the sensor under different frequencies and stroke displace-ments to show the capability of the fabricated device as a self-poweredsensor. Furthermore, the authors evaluate the durability and performance ofthe sensor to delineate its potential for tire condition monitoring. The resultsshow that the fabricated self-powered sensor has the potential of measuringthe tire forces and pressure. The use of the proposed sensor for tirecondition monitoring systems (TCMS) can be considered as a significant steptoward developing smart tires, improving vehicles control strategy, andaccordingly, enhancing passengers safety.
