Energy Harvester generates electricity from inside spinning tyres

A new technology that could see tyres generate electricity whilst driving is being developed by engineers in Japan. Falken’s parent company, Sumitomo Rubber Industries, together with Professor Hiroshi Tani of Kansai University, have developed the Energy Harvester that takes advantage of the build up of static electricity, known as frictional charging, to produce power efficiently as the tyre turns.

Inside the Energy Harvester are two layers of rubber each covered in an electrode, along with a negatively charged film that interfaces with a positively charged film. When fixed to the inside of a conventional tyre carcass it generates electricity as the tyre deforms during rotation.

Engineers believe the Energy Harvester could lead to practical applications as a power source for sensors used in TPMS (Tyre Pressure Monitoring Systems) and other automotive devices without the need for batteries.

It was created as part of Sumitomo’s R&D programme to develop technologies that target improvements in safety and environmental performance. Now, the research has been selected by the Japan Science and Technology Agency (a national research and development agency) as a Type FS Seed Project under A-STEP (Adaptable and Seamless Technology Transfer Program through Target-Driven R&D). Sumitomo Rubber Industries will now advance this research with support from the Japan Science and Technology Agency.

Falken Tyre Europe GmbH is the European affiliate of Japanese tyre manufacturer Sumitomo Rubber Industries Ltd. (SRI); with more than 37,852 employees, it is the fifth largest tyre manufacturer worldwide.

In 2001 and 2014 SRI was selected to appear in the Thomson Reuters ‘Top 100 Global Innovators’ list of the world’s most pioneering companies.

From its location in Offenbach, Main, the company markets and sells a complete tyre portfolio for passenger cars, light trucks, trucks, pick-ups and SUVs as original equipment and for the entire European retrofitting market.

The Falken brand is involved in exciting and high technology platforms such as motorsport with a Porsche 911 GT3 R and BWM M6 GT3, Red Bull Air Race, at the AUDI Sportpark stadium, which is the stadium of Bundesliga club FC Ingolstadt 04, and as the global tyre partner of Liverpool FC, as well as the official tyre partner of FC Schalke 04.
