The Fundamentals of Dispersive Signal Touch Sensors
A touch sensor is a type of equipment that captures and records changes in a physical quantity by converting it into signals which can be easily measured and analyzed. Among numerous types of touch sensors, the Dispersive Signal Touch Sensor has gained notable attention due to its distinct methodology and functionality.
Understanding the Concept of Dispersive Signal
The key concept behind a dispersive signal touch sensor revolves around the use of mechanical waves, specifically the dispersion of these waves. In physical terms, dispersion is the phenomenon where wave speed depends on frequency. In these sensors, dispersion of a mechanical wave is typically used for identifying the touch location on the sensor surface.
Operation of Dispersive Signal Touch Sensors
Dispersive signal touch sensors operate by emitting a wave into the substrate when the screen is touched. The touch generates a wave that propagates throughout the surface of the sensor. This wave then reaches the corners of the screen where sensors are located. The time taken by the wave to reach these sensors is calculated, and this time difference aids in determining the exact location of the touch.
