SparkFun Flex Sensor 4.5"

One directional Flex Sensor is a unique component that changes resistance when bent or flexed (Patent 5086785). An un flexed sensor Style A has a nominal resistance of approximately 10,000 ohms (10 K). As the flex sensor is bent in one direction the resistance gradually increases. Range of resistances of the FLX-03 Style A sensor may vary between 10K and 40K depending upon the degree of the flex. An un flexed sensor Style B begins with a infinitely high nominal resistance. As the flex sensor is bent in one direction the resistance gradually decreases. Range of resistances of the FLX-03 Style B sensor may decrease to under 10K depending upon the degree of the flex. The flex sensor operating temperature is -45F to 125F. The flex sensor operating temperature is -45F to 125F. Style A Connection - Pin connector. 100" spacing Style B Connection - 2 Position socket mates to 2-position header. 100" spacing The sensor measures 1/4 inch wide, 4 1/2 inches long and only .019 inches thick!
A simple flex sensor 4.5" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol - they claim these sensors were used in the original. Nintendo Power Glove. I love the Nintendo Power Glove. It's so bad! The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on inside of bend). Straight (unflexed) resistance: ~9000 Ohm 90 degree bend resistance: ~14000 Ohm 180 degree bend resistance : ~22000 Ohm Connector is 0.1" spaced and bread board friendly.
