A simple flex sensor 2.2" in length. As the sensor is flexed, the resistance across the sensor increases.The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on the inside of bend). The connector is 0.1" spaced and breadboard friendly.

These 2.2" Flex Sensors can be easily integrated to an Arduino or Raspberry Pi by making a voltage divider circuit using a 10 K Ohm resistor at any one lead of the sensor. Flexion sensors, (from Latin flexure, 'to bend') also called bend sensors, measure the amount of deflection caused by bending the sensor. There are various ways of sensing deflection, from strain-gauges1) to hall-effect sensors2).
