At a time when the Covid pandemic has drawn focus to the potential spread of infections through the use of touch screen devices like smartphones, scientists here have come up with an solution in the form of a low-cost touch-cum-proximity sensor popularly called touch-less touch sensor, through a printing technique.

Scientists from the Centre for Nano and Soft Matter Sciences (CeNS), and Jawaharlal Nehru Centre for Advanced and Scientific Research (JNCASR) in Bengaluru have set up a semi-automated production plant for the production of printing-aided patterns, with resolution of around 300 Aum. These electrodes have potential uses in advanced touchless screen technologies.
