A flex sensor or bend sensor is a sensor that measures the amount of deflection or bending. Usually, the sensor is stuck to the surface, and resistance of the sensor element is varied by bending the surface. It is very useful when we’re required to measure the extent of bending in anything. As the sensor bends, its resistance increases and that is how it measures the amount of bend applied.
A flex sensor has a flexible material which is bent to find out the extent of bending, and two terminals that are connected to the circuit.
How to use
A flex sensor basically works with varying resistance as the flexible material is bent.
