MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202631059447 A) filed by Dr. Sudhir Chandra Sur Institute Of Technology & Sports Complex, Kolkata, West Bengal, on May 10, for 'led-assisted graphene oxide-based ethylene sensor.'
Inventor(s) include Dr. Shayari Basu; Ms. Debasmita Roy Chowdhury; Ms. Nibedita Biswas; and Mr. Saswata Ray.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "An LED-assisted graphene oxide (GO) based ethylene sensor is disclosed for high-sensitivity monitoring of fruit ripeness and post-harvest produce. The sensor utilizes a graphene oxide sensing layer deposited on interdigitated electrodes, where the electrical response is modulated by low-power LED illumination. The adsorption of ethylene gas on the GO surface alters the transport of photo-generated charge carriers, enabling a dual-mode sensing mechanism through the comparison of electrical signals in dark and illuminated conditions. The invention facilitates room-temperature operation, enhanced wavelength-dependent selectivity, and ultra-low power consumption, effectively eliminating the need for traditional thermal activation elements."
