MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641050857 A) filed by Indian Institute Of Technology, Chennai, Tamil Nadu, on April 21, for 'self-powered wound-healing system with hybrid nanogenerator-driven drug release.'
Inventor(s) include Arockiarajan Arunachalakasi; Swathi Sudhakar; Shaikh Faruque Ali; Sayyid Abdul Basith Valiyakkathodi; and Renugaa Suresh Babu.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a self-powered hybrid nanogenerator-hydrogel system (100) for electrical stimulation-assisted drug release and wound healing. The system (100) includes a flexible hybrid nanogenerator comprising a corona-poled polyvinylidene fluoride-co-hexafluoropropylene composite film incorporated with lead-free caesium silver bismuth bromide nanoparticles, a power-conditioning circuit, and a biocompatible chitosan-based hydrogel loaded with ciprofloxacin and optionally graphene oxide. The hybrid nanogenerator harvests low-frequency mechanical energy and generates electrical output through combined piezoelectric and triboelectric effects, and the conditioned electrical signal is delivered to the hydrogel to trigger controlled and on-demand drug release. The system (100) is configured as a decoupled, battery-free, wearable therapeutic platform in which the energy-harvesting unit remains external to the wound region while the hydrogel dressing contacts the wound surface. The invention provides enhanced electrical output, accelerated drug release, antibacterial activity, and improved wound closure."
