This force sensor is an ultra-thin, flexible printed circuit. The standard A201 force sensor is constructed of two layers of substrate (polyester) film. The high-temp model (HT201) is constructed of two layers of polyimide.
On each layer, a conductive material (silver) is applied, followed by a layer of pressure-sensitive ink.
Adhesive is then used to laminate the two layers of substrate together to form the force sensor.
The active sensing area is defined by the silver circle on top of the pressure-sensitive ink. Silver extends from the sensing area to the connectors at the other end of the sensor, forming the conductive leads.
A201 sensors are terminated with male square pins, allowing them to be easily incorporated into a circuit. The two outer pins of the connector are active and the center pin is inactive.
