MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511114563 A) filed by Dr. Praveen Chandra Jha; and I. T. S Engineering College, Greater Noida, Uttar Pradesh, on Nov. 20, 2025, for 'biodegradable conductive shellac-based ink for disposable printed electronics.'
Inventor(s) include Dr. Praveen Chandra Jha.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a biodegradable conductive ink composition utilizing shellac resin as a natural binder integrated with metallic or carbon-based conductive fillers such as silver flakes, copper nanoparticles, or grapheme Conductive Carbon nano powder. The formulation is designed for application in disposable and paper-based printed electronics, offering a sustainable and eco-friendly alternative to conventional synthetic polymer-based conductive inks. The ink exhibits strong adhesion to cellulose-based substrates, excellent printability, and stable electrical conductivity while remaining water-insoluble after drying. It can be processed through conventional screen, flexographic, or inkjet printing techniques using low-toxicity solvents like ethanol or isopropyl alcohol. By leveraging the hydrophobic and film-forming properties of shellac, the invention enables the fabrication of biodegradable electronic devices such as RFID tags, sensors, and paper circuits that decompose harmlessly after use, thereby reducing electronic waste and supporting sustainable manufacturing."
