This Sensor measure the mechanical Stress apply to its tip. When you press the sensor it resistor changes from infinity to about 300K ohm. It is Flexible and the output resistance does not changes if you bend it. it has three pins , but only use 2 pins just like resistor.
FlexiForce™ force sensors can measure force between almost any two surfaces and are durable enough to stand up to most environments. Our sensors are available off-the-shelf for prototyping or can be customized to meet the specific needs of your product design and application requirements.
FlexiForce sensors are utilized in many applications to detect and measure:
Relative change in force or applied load
Rate of change in force
Force thresholds and trigger appropriate action
Contact and/or touch
