MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641061851 A) filed by Vignan's Foundation For Science, Technology And Research, Guntur, Andhra, on May 15, for 'hybrid energy harvesting using piezoelectric and thermoelectricity for bikes.'
Inventor(s) include Rentapalla Bala Murali Krishna; Nalluri Naga Lakshmi; Ramineni Gayathri Sai; Shaik Barkat Basha; and Dr Naga Srinivasarao Chilamkurthy.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "Two-wheelers inherently waste large amounts of mechanical and thermal energy in standard operations due to road-induced vibrations, suspension travel, braking events, and thermal generation from brakes, engine, motor, and exhaust components. The proposed idea introduces a hybrid energy harvesting approach that captures these wasted sources of energy for motorcycles through combined piezoelectric and thermoelectric energy harvesting mechanisms for conversion into useful electrical power. Piezoelectric sensors are adopted for vibration energy harvesting from suspension assemblies, braking mechanisms, and frame oscillations, whereas thermoelectric generators take advantage of temperature gradients available in brake discs, engine blocks, exhaust systems, and motor casings. The conditioned signals, obtained using rectification, voltage regulation, and energy management circuits, are stored in rechargeable batteries or super capacitors. The hybrid system proposed here ensures improved energy availability across different riding conditions, operational reliability, and reduced reliance on conventional batteries. An analytical analysis and system-level analysis show the system can provide adequate power to a low-power electronic subsystem to explore sustainable, self-powering, smart bicycle applications."
