MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641050518 A) filed by Sona College Of Technology, Salem, Tamil Nadu, on April 21, for 'system and method for piezoelectric energy harvesting module for autonomous internet of things device.'
Inventor(s) include Karthik B; and Shanmugasundaram V.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a system and method for a piezoelectric energy harvesting module for autonomous Internet of Things (IoT) devices. The system comprises at least one piezoelectric transducer mechanically coupled to a vibrating structure, a rectifier converting the transducer's alternating output to a rectified voltage, and a power management circuit that charges an energy storage element such as a supercapacitor or rechargeable cell. A supervisory circuit monitors the storage voltage and controls a load switch that connects a regulated power output to an IoT device only when the storage voltage exceeds an enable threshold and disconnects the load when the storage voltage falls below a lower threshold. The module provides energy-good and optional low-energy control signals to the IoT device, enabling energy-aware duty cycling. Mechanical and electrical tuning options widen the effective harvesting bandwidth. The system thereby enables long-term, battery-less or battery-assisted operation of IoT devices using ambient vibration energy."
