MUMBAI, India, Nov. 21 -- Intellectual Property India has published a patent application (202511076997 A) filed by Indian Institute Of Technology, Kanpur, Uttar Pradesh, on Aug. 13, for 'a hybrid flexible chemiresistive sensor for ethylene gas detection.'
Inventor(s) include Ajithkumar Manayan Parambil; and Siddhartha Panda.
The application for the patent was published on Nov. 21, under issue no. 47/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to a hybrid flexible chemiresistive sensor for ethylene gas detection and a method for its fabrication. The sensor includes a flexible substrate, electrodes, a first active layer of screen-printed polyaniline (PANI), and a second active layer printed on the first layer. The second layer comprises a complex of single-walled carbon nanotubes (SWCNT) and Tetrakis(acetonitrile)copper(I) hexafluorophosphate (TACHFP), which selectively interacts with ethylene gas. The sensor operates at room temperature, enabling use on low-cost flexible substrates. The interaction of ethylene with the second layer modulates the electrical resistance of the PANI layer, allowing for sensitive and selective detection down to 1 ppm. The sensor is suitable for applications in agricultural monitoring, such as assessing fruit ripeness, to improve food quality control."
