Static electricity-based 'In-tire Power Generation Technology'

Successful development of battery-less tire perimeter sensors! Introducing tire internal power generation technology utilizing static electricity.

A joint development by Sumitomo Rubber Industries, Ltd. and Kansai University has been undertaken to realize the "tire internal power generation technology." We have successfully extracted electric power from the movement of charges generated by the triboelectric effect between positively and negatively charged films within the tire. By incorporating a power control circuit, we added the functionality to charge power from the power generation device. This enables power supply to sensors that require batteries, such as batteries. Additionally, the tire internal power generation technology could be one solution to the battery life issue of external sensor devices. 【Features】 ■ Generates power through tire rotation ■ Charges the power control circuit and confirms power supply to external sensors ■ Enables sensing without batteries ■ Ensures durability to withstand harsh conditions within the tire ■ Allows power supply to sensors that require batteries *For more details, please refer to the PDF document or feel free to contact us.
