A touch sensor, a key part of the sensors and transducers category, is an equipment that captures and records physical touch or embrace on a device or object. It primarily functions to measure the amount of touch or force applied on the surface and convert it into an electric signal. The sensors pick up specific physical touch, pressure, or impacts and transform it into a readable input for a device. They are commonly found in many devices from smartphones and laptops to industrial machines and home appliances, offering a seamless interface for interaction.
The touch sensors are designed for a variety of applications, catering to different needs. For instance, capacitive touch sensors are used in touchsCreen devices such as smartphones and tablets due to their high sensitivity and quick response time. They are also utilized in industrial applications for touch panels, control switches, and household appliances. Meanwhile, resistive touch sensors, known for their durability and versatility, are often employed in POS terminals and public information kiosks. Regardless of the application, touch sensors provide a user-friendly interface and enhance the overall efficiency and accessibility of the device. Some leading manufacturers of touch sensors include Honeywell, Siemens, and TTI.
