Large Area Pressure Sensor for Smart Floor Sensor Applications—An Occupancy Limiting Technology to Combat Social Distancing

Abstract

With the advent of the recent coronavirus pandemic, it has become crucial to maintain social distancing within public spaces. To achieve this, it is important to keep a count of the number of people entering the premises and maintain low occupancy within it. This article presents a very large area pressure sensor based on nickel sulfide deposited on a paper using facile hydrothermal, and sheet to sheet vacuum filtration technique followed by an encapsulation of the sensor using polydimethylsiloxane for smart floor applications. An android application is also developed for the count of the people and the estimated waiting period for the entry.
