MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202611057934 A) filed by Panipat Institute Of Engineering And Technology Piet on May 07, 2026, for Public Transport Seat With Hybrid Triboelectric–piezoelectric Energy Harvesting For Passenger Motion Power.
Inventor includes Mr. Anurag Vashist.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: The present invention a public transport seat is disclosed with an integrated hybrid triboelectric and piezoelectric energy harvesting system that generates electrical energy from passive passenger micro-movements and vehicle vibration. The seat cushion includes triboelectric frictional layers that generate charge through contact and separation during posture shifts and low-frequency motion. A piezoelectric mesh network embedded in the seat base converts compression and vibration into electrical output. The generated signals are conditioned using an AC-to-DC rectifier, voltage regulator, and charge controller, and stored in an energy storage unit comprising a supercapacitor and/or rechargeable battery. A utilization module provides regulated power to auxiliary onboard loads such as USB charging ports, LED seat illumination, and emergency indicator lighting. The system is modular and can be retrofitted as a plug-and- play seat energy node across multiple seats in buses, trains, and metro coaches, enabling distributed micro-generation without additional passenger effort and reducing auxiliary power draw from vehicle electrical systems.
