Inventor(s) include Dr. S. L. Prathapa Reddy; Dr. G. Suneel Kumar; Dr. K. Pavan Kumar; Dr. V. Vijaya Kishore; Dr. G. Srihari; and Dr. M. Madhusudhan Reddy.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "This invention introduces a novel RF energy-harvesting circuit architecture designed to enable self-powered operations by efficiently scavenging ambient electromagnetic waves and converting them into DC power for sensor nodes. The framework features a compact, integrated circuit with advanced rectification stages and voltage multipliers that optimize energy extraction across varying RF signal strengths, yielding harvest efficiencies exceeding 50% even in low-power density scenarios. By leveraging CMOS-compatible processes, the design ensures cost-effective scalability while incorporating smart control logic for dynamic power allocation to sensors and transmitters. Prototype evaluations under simulated real-world conditions, including indoor and outdoor RF environments, reveal a threefold increase in operational uptime compared to battery-dependent alternatives, alongside robust performance against interference. the invention's role in advancing autonomous IoT applications, such as environmental monitoring and asset tracking, by providing a reliable, battery-free power source that enhances network longevity and reduces ecological impact."
