Researchers at a private university in Uttar Pradesh's Noida have developed smart devices that raise alarm when social-distancing norms are breached and a user touches their face, besides designing gloves that dispense sanitiser automatically. The wearable-devices are affordable and operate on battery, they said, claiming they can be effective in fighting the spread of the novel coronavirus. The device for social-distancing alarm can be worn like a wrist band and warns users if someone comes closer than six feet to them, according to the research scientists at Amity University, Noida.

"It's a handy, small, portable, low-cost, low-powered battery-operated smart electronic device. This electronic device can maintain the social distance of 6 feet between two persons by giving signal through buzzer and light indications alarm. It warns both the persons, having the same device, if violating the social distancing conditions," the varsity said. "The pocket-friendly device is in the form of a band and can be worn like a wrist watch which will work even if a group of people is coming closer from multiple directions. Each unit of this invention will cost around Rs. 400-500 and the option of chargeable battery can also be easily made in these devices," it said.
