Touch Sensors

Capacitive touch sensors are electronic components used to detect and respond to touch or proximity without the need for physical pressure. They utilize the principle of capacitance, measuring changes in the electrical charge when a conductive object, such as a finger or stylus, comes in close proximity to the sensor’s surface.

Capacitive touch sensors are commonly used in various applications, including touchscreens, touch panels, interactive displays, smartphones, tablets, home appliances, automotive systems, and industrial control panels. They offer advantages such as high sensitivity, fast response times, multi-touch capability, and durability.

Resistive touch sensors are electronic components used for touch input and control. They consist of multiple layers, typically two flexible sheets coated with a resistive material and separated by a small gap. When pressure is applied to the top layer, it presses against the bottom layer, causing electrical contact at a specific location.

Resistive touch sensors work based on the principle of changes in electrical resistance. The layers have a conductive coating with a resistive material that forms a voltage divider. When pressure is applied, the layers come into contact, creating a change in resistance at the precise touch point. The controller detects this change and determines the location of the touch.

Infrared (IR) touch sensors, also known as infrared touchscreens, are electronic devices that detect touch input through the interruption of infrared light beams. These sensors consist of an array of infrared light-emitting diodes (LEDs) and photodetectors positioned around the screen’s edges.

IR touch sensors work by emitting infrared light beams across the surface of the screen. When a user touches the screen, it interrupts the infrared beams, and the photodetectors detect the interruption, determining the touch location. The sensors can detect multiple touch points simultaneously, enabling multi-touch functionality.

Force-Sensing Resistors (FSR) are electronic components that change their resistance in response to the applied force or pressure. They are designed to measure and detect force or pressure variations at specific points or areas.

FSRs typically consist of a flexible polymer film with conductive material on its surface. When force is applied to the sensor, the conductive particles within the film come into contact, causing a decrease in resistance. The amount of force or pressure applied can be determined by measuring the change in resistance.
