In an exciting development for the future of electronics, researchers from BITS Pilani’s Hyderabad campus have created a new eco-friendly material that could revolutionize wearable technology. This innovative material, a metal-decorated 3D graphene composite, was developed using a unique laser method that is both clean and cost-effective.
The research team, supervised by Sanket Goel from the Department of Electronics and Electrical Engineering, used a process that requires no harmful gases, toxic chemicals, or extremely high temperatures. Instead, they worked with a flexible material called metal-polyimide films, which can be combined with other affordable materials like paper and fabric. This means the new composite can be used in various applications, including wearable devices, disposable electronics, and on-the-go gadgets.
One of the most impressive features of this new composite is the way it integrates metal nanoparticles, specifically silver and gold, into the structure. This creates a highly porous and conductive material with multifunctional capabilities. Researchers found that it can be used for detecting Vitamin C, has antibacterial properties, and shows potential for applications in fuel cells, supercapacitors, and biosensors.
The process developed by the team allows them to produce 1 milligram of this material in just five minutes, and it costs between ₹0.07 and ₹0.13 per milligram, depending on the type of metal used. Research scholar Nishchitha NK emphasized that this innovative method can support the increasing demands of both energy and healthcare systems in a sustainable way.
Dr. Goel highlighted the importance of their work, stating, “Creating this new material enables a future where eco-friendly fabrication methods can meet the growing demands of energy and healthcare systems.” Their research reflects the global shift towards nanomaterials and flexible electronics, paving the way for next-generation applications.
The team’s pioneering work has been recognized with an Indian patent and is set to be published in the respected international journal Applied Surface Science.
