Force 4 Click is based on HSFPAR003A piezoresistive force sensor from Alpsalpine. This product is a force sensor using the effect of a piezoresistive bridge circuit formed on silicon diaphragm. Piezoresistive force sensors achieve higher linearity than other force sensors to help with stability and accuracy. It also includes MCP1101-33 a high precision buffered voltage reference as a power supply to a force sensor that allows high stability and accuracy of output voltage readings.
Force 4 Click has high sensitivity and good linearity. It precisely detects micro force less than 0.01 N, and there are no characteristics change after 1 million cycles.
