Touchsensors

A touch sensor is a type of equipment that captures and records physical touch or embrace on a device and/or object. It is a crucial part of devices that we have come to rely on, such as control panels e.g. for white goods or industry, HMI interfaces, bounce-free buttons, and many other interactive devices.  Also known as tactile sensors, it’s a small, simple, low-cost sensor made to replace old mechanical switches we seen in the past.

A touch sensor works like a switch, where when there’s contact, touch, or pressure on the surface of a touch sensor, it opens up an electrical circuit and allows currents to flow through it.

Types of touch sensor:

  • Capacitive touch sensor
  • Resistive touch sensor
  • Infrared touch sensor
  • Surface acoustic wave (SAW) touch sensor
  • Inductive touch sensor
