Japanese Tire Company Unveils New Method To Create Electricity From Tire Friction | Innovation Discoveries

The idea to capture the energy in and around the wheels of a car while it makes its way on the road is surely amazing and interesting. The idea was addressed by the titans in tire manufacturing such as Goodyear with its BH03 concept back in 2015. However, Japan’s Sumitomo Rubber is coming with a new possibility. This tire design would allow the company to leverage the friction down below for the production of electricity for the accessories of the vehicles that are on board.

The tire concept that harvests the energy of the friction by Sumitomo Rubber came to be because of a collaboration between the company and Japan’s Kansai University. Teams of researchers from both worked together to create a system that comprises of a regular car tire and a special energy harvesting device that gets planted inside it.

Two layers of rubber with each being covered in an electrode exist in the device along with a film that is negatively charged and interfaces with a film that is positively charged. As the tire starts to roll on the ground and its footprint gets deformed; it creates a kind of static electricity that is known as frictional charging…Continue Reading
