J; Mayil Vannan V. B; Tamil Selvan B; Sarugesh A; and Girivasan A, Coimbatore, Tamil Nadu, on Dec. 29, 2025, for 'renewable energy integrated gym equipment with iot monitoring.'
Inventor(s) include Dr V Tamilselavan; Mathivel. J; Mayil Vannan V. B; Selvan B; Sarugesh A; and Girivasan A.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The Piezoelectric Energy Harvesting Lat Pull-Down Machine is an innovative approach to transforming mechanical workout energy into usable electrical power. In conventional fitness equipment, substantial mechanical energy generated by users during exercise is wasted as heat and motion. This project introduces a sustainable solution by integrating piezoelectric transducers at high-stress points of a lat pull-down machine to capture and convert mechanical stress into electrical energy. The generated voltage is amplified through a DC-DC boost converter, monitored using voltage sensors, and managed by an ESP32 microcontroller with IoT connectivity. The harvested energy is stored in a 12V lithium-ion battery for later use in powering gym utilities such as lights or display systems. This system not only promotes green energy generation within fitness centers but also enhances user motivation by displaying real-time energy contributions. Offering a low-cost, eco-friendly, and retrofit-capable design, the project supports India's vision of sustainable smart gyms and contributes to the broader goal of renewable energy innovation."
