Description

TOUCH SENSOR:-

A Touch sensor is a type of device that captures and records physical touch or embrace on a device and/or object. It enables a device or object to detect touch or near proximity, typically by a human user or operator. Touch sensors are also called as tactile sensors and are sensitive to touch, force or pressure.

There are two common types of touch sensors :

  1.  Capacitive touch sensors
  2.  Resistive touch sensors.

These sensors are sensitive to any pressure or force applied or touch. The principle of touch is similar to that of a switch. When the switch is closed, the current flows otherwise there is no chance of the current to flow. Similarly, when the touch sensor senses the touch or proximity is captured then it acts like a closed switch otherwise it acts as an open switch. These sensors are also known as ‘Tactile Sensors’
