Note: for the 4.5″ flex sensor, please refer to: 4.5″ flex sensor


  • A simple Sparkfun flex sensor 2.2″ 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).
  • Connector is 0.1″ spaced and bread board friendly. Check datasheet for full specifications.
Note: The latest version of this product varies on resistance. Please be careful when bending the wiring side of the sensor and note the change on the resistance.
