This ultra-thin capacitive force sensor 8 mm 100N 22lbs by SingleTact is very accurate with a repeatability error less than 1% of FSR. It is not only the world’s first capacitive miniature force sensor but it also delivers superior sensitivity and repeatability over resistive force sensors. The single-element capacitive sensor accurately and reliably quantifies forces and delivers incredible performance.
Only 0.35mm thick, these enable you to collect force and pressure measurements between two surfaces in contact through open source sample code for Arduino and Windows PC application or using a simple Analog 3-wire interface for immediate DAQ integration.
Note: Measuring capacitance can be challenging so we recommend that you use the capacitive force sensor electronics board to provide a convenient voltage output and a digital I2C interface.
