New Device That Generates Electricity from Tires

Scientists at the CSIR–Indian Institute of Chemical Technology have developed an innovative self-charging device that generates electricity from the continuous movement and vibrations of vehicle tires. If commercialized, this technology could eliminate the need for batteries in small sensors and smart vehicle components. The research, led by Dr. Ujwal Paul, has been published in the journal Advanced Functional Materials.

The system is based on a triboelectric nanogenerator (TENG) “power wheel” that converts mechanical energy from tire motion and heat into electrical energy. Researchers introduced key improvements using metal-organic frameworks, 3D printing technology, and a smart integrated design. The innovation can power tire pressure sensors, brake sensors, and other electronic components without external batteries, reducing waste and improving efficiency.
