**Headline: Indian Researchers Develop Eco-Friendly Method for Low-Cost Flexible Electronics**

**Hyderabad, India – June 19, 2025** – Researchers at BITS Pilani, Hyderabad, have announced a breakthrough in flexible electronics manufacturing with the development of a metal-decorated 3D graphene composite. The innovative method utilizes an eco-friendly laser-induced process on flexible metal-polyimide films, eliminating the need for toxic chemicals, harsh conditions, or high temperatures.

Led by Dr. Sanket Goel, the research team created the in-situ laser technique that integrates metal nanoparticles, like silver and gold, within the polyimide. This results in a highly porous, conductive, and multifunctional graphene composite suitable for use with other affordable and bendable materials like paper and fabric. This opens exciting new possibilities for wearable, disposable, and on-the-go electronics.

“We have developed a fast, clean, and cost-efficient process that produces 1 mg of material in just five minutes, at an estimated cost of ₹0.07–₹0.13 per mg,” said research scholar Nishchitha NK.

The resulting material has demonstrated promising applications, including Vitamin C detection, antibacterial activity, and potential use in fuel cells, supercapacitors, and biosensors. The researchers emphasized that the method creates 1mg of the material within 5 minutes and is estimated to cost between 7 to 13 paisa, depending on the metal used.

“Creating this new material enables a future where eco-friendly fabrication methods can meet the growing demands of energy and healthcare systems,” stated Dr. Goel, highlighting the innovation’s alignment with the global push for nanomaterials and flexible electronics.

The team’s work has already secured an Indian patent and has been published in the international journal *Applied Surface Science*. The eco-friendly process represents a scalable and chemical-free route to next-generation electronic applications.
