Flex Sensors are commonly used in Robotic Gloves and other Robotic Control application. It can be used to analyze how much a material is being bent. This flex sensor is 2.2” long and has two output leads which acts 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. Technical Specifications: Operating  voltage: 0-5V Flat Resistance: 25K Ω Resistance Tolerance: ±30% Operating temperature: -45ºC to 80ºC Power rating: 0.5Watt (continuous), 1 Watt (peak) Package Includes: 1 Piece-Thin Film Pressure Sensor -Round 18mm OD
