MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202531100246 A) filed by Guru Nanak Institute Of Technology, Kolkata, West Bengal, on Oct. 16, 2025, for 'thermally resistant sensor system for detection and control of vegetable-derived gases in refrigerated environments.'
Inventor(s) include Mr. Moloy Dhar; Dr. Amrut Ranjan Jena; Dr. Srijan Sengupta; Mr. Shuvodeep Debnath; Sourish Modak; Tanzil Haider; and Shivam Kumar Sha.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure discloses a smart refrigerator system equipped with an integrated gas-sensing and neutralization mechanism for preserving perishable goods. The system comprises a plurality of semiconductor-based gas sensors, each adapted to detect spoilage-indicating gases including ethylene, ammonia, hydrogen sulfide, and carbon dioxide. The sensors are provided with micro-heater assemblies and catalytic materials to enable functionality at refrigeration temperatures. A microcontroller processes real-time sensor data compares gas concentrations against threshold values, and actuates a relay-controlled neutralization system comprising potassium permanganate, limewater, ozone, and activated carbon filters. The system operates autonomously to delay ripening, reduce odors, and extend the freshness of stored goods, thereby addressing deficiencies of prior art refrigeration systems that rely solely on passive cooling."
