2.2inch Flex Sensor

Flex Sensor 2.2″ Bend Sensor for Hand Gesture Recognition
The 2.2-inch Flex Sensors are commonly used in Robotic Gloves and other Robotic Control applications. It can be used to analyze how much material is being bent. This flex sensor is 2.2” long and has two output leads that act like a variable resistor. That is the resistance between two pins change based on how much the sensor is bent.  It is commonly used along with another resistor to build a voltage divider circuit and then obtain a variable voltage based on the change in resistance of the sensor.
The flex sensor is a bend-detecting sensor that has got numerous applications in robotics, medical and haptic technology. The resistance of these sensors changes in accordance with the bend, which can be measured using any microcontroller.
This is a simple 2.2″ long flex sensor that can be used/interfaced with an Arduino. 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 inside of the bend). The connector is 0.1″ spaced and breadboard friendly. 
Note: Please refrain from flexing or straining this sensor at the base. The usable range of the sensor can be flexed without a problem, but care should be taken to minimize flexing outside of the usable range. For best results, securely mount the base and bottom portion and only allow the actual flex sensor to flex.
