(GIST OF SCIENCE REPORTER) Touchless Touch Sensor

[JULY-2022]

Scientists from the Centre for Nano and Soft Matter Sciences (CeNS) and Jawaharlal Nehru Centre for Advanced and Scientific Research (JNCASR), have developed a low-cost touch-cum-proximity sensor. They have come up with a semiautomated production plant which can be used in advanced touchless screen technologies.
The touchless touch sensor can sense a proximal or hover touch even from a distance of 9 cm from the device. This technology helps minimise the spread of viruses that spread through contact. This work was published in the journal Materials Letters.
