Indian scientists have come up with an affordable solution to develop a low-cost touch-cum-proximity sensor popularly called touchless touch sensor through a printing technique.</p>
<p>
The breakthrough comes at a time when the coronavirus pandemic requires measures to reduce the risk of viruses spreading, particularly in public places where touchscreens on self-service kiosks, ATMs, and vending machines are nearly inevitable.</p>
<p>
Work done by an Indian team of scientists led by Prof. G U Kulkarni and co-workers and funded by DST-Nano mission at CeNS has been published recently in the journal &lsquo;Materials Letters&rsquo; recently. Dr. Ashutosh K Singh, a scientist working on this project, said, &ldquo;We have fabricated a touch sensor which senses a proximal or hover touch even from a distance of 9 cm from the device&rdquo;.</p>
<p>
&ldquo;We are making a few more prototypes using our novel low-cost patterned electrodes to prove their feasibility for other smart electronic applications. These patterned electrodes can be made available to interested industries and R&amp;D labs on a request basis to explore collaborative projects,&rdquo; said Dr. Indrajit&nbsp; Mondal, another co-author in the research.</p>
<p>
Recently Bengaluru-based scientists from the Centre for Nano and Soft Matter Sciences (CeNS), and the government&rsquo;s Jawaharlal Nehru Centre for Advanced and Scientific Research Government have set up a semi-automated production plant for the production of printing-aided patterned (resolution of around 300 &micro;m) transparent electrodes, which has the potential for being utilized in advanced touchless screen technologies.</p>
