MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202521125128 A) filed by Vivek Raut; Dipankar Pimple; Vinayak Musale; Pranav Navandar; Amruta Amune; Pratham Tomar; and Prachi Shirode, Pune, Maharashtra, on Dec. 11, 2025, for 'a self-powered energy harvesting hinge system for smart infrastructure and iot applications.'
Inventor(s) include Vivek Raut; Dipankar Pimple; Vinayak Musale; Pranav Navandar; Amruta Amune; Pratham Tomar; and Prachi Shirode.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a self-powered energy harvesting and intelligent monitoring system that converts mechanical motion from a door hinge into usable electrical energy and simultaneously enables real-time data transmission through an Internet of Things (IoT) framework. The system comprises a plurality of micro dynamo-based direct current (DC) generators mechanically coupled to a door hinge shaft for converting rotational kinetic energy into electrical output. The generated electrical signal is conditioned using a full-wave bridge rectifier and a voltage boost regulation circuit to produce a stable direct current supply. The conditioned power is stored in a rechargeable energy storage unit comprising a lithium-ion battery and an optional supercapacitor, managed by a controlled charging and protection circuit. A microcontroller-based control unit continuously monitors voltage, current, and door movement parameters using dedicated sensors, including a Hall Effect sensor. A wireless communication module transmits the processed data to a remote cloud server, enabling real-time visualization, analytics, and alert notifications through web and mobile platforms. The invention provides a compact, autonomous, and maintenance-efficient solution capable of harvesting otherwise wasted mechanical energy from routine door operations while simultaneously functioning as a self-sustained IoT sensor node. The system enhances energy efficiency, enables predictive usage analytics, and eliminates the requirement for external power sources, making it highly suitable for smart buildings, security systems, and industrial monitoring applications."
