Bhubaneswar, Jan. 10 -- In a significant step towards affordable and sustainable sensor technology, researchers at Gauhati University have developed a flexible, low-cost sensor using simple materials such as pencil, paper and graphene. The innovation holds promise for wide-ranging applications in hospitals, farms and wearable health monitoring.

The research, led by Dr Hemen Kumar Kalita of the Department of Physics along with his PhD scholars Rajnandan Lahkar and Biswajit Dehingia, addresses the growing demand for economical and scalable sensors. Unlike conventional sensors that rely on rigid substrates, expensive metals like gold or platinum, and complex manufacturing processes, the newly developed sensor is designed to be simple, flexi...
