Pressure mapping sensors are ultra-thin pressure-sensitive resistors (aka, tactile array sensors) that are used capture pressure data between nearly any two surfaces. Each sensor consists of intersecting rows and columns of conductive material. At each intersection is a layer of pressure-sensitive material. As pressure is applied to the sensing area, the resistance of the pressure-sensitive material changes. Scanning electronics connected to the sensor collects and converts this resistance change into digital signal, which is then transmitted to a computer for real-time analysis.
Want to know how our pressure mapping sensors are made, and how they work? This short video provides a visual overview of Tekscan's pressure mapping sensor technology, and also what happens when the sensor receives pressure.
