The FlexiForce sensor is an ultra-thin and flexible printed circuit, which can be easily integrated into most applications. With its paper-thin construction, flexibility and force measurement ability, the FlexiForce force sensor can measure force between almost any two surfaces and is durable enough to stand up to most environments.

FlexiForce has better force sensing properties, linearity, hysteresis, drift, and temperature sensitivity than any other thin-film force sensors.

The "active sensing area" is a 0.375” diameter circle at the end of the sensor.


This FSR connects to an InterfaceKit or Hub through a FlexiForce adapter. See the Connection & Compatibility tab for details.

Flexiforce Adapter

This force-sensitive resistor can be interfaced to your InterfaceKit or Hub using a Flexiforce adapter. Just plug the FlexiForce sensor into the cable provided with the adapter, and clamp the other end into the terminal block.
