A simple flex sensor 4.5" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol. The resistance of the flex sensor changes when the metal pads are on the outside of the bend (the text on the inside of bend).
- Straight (unflexed) resistance: ~9000 Ohm
- 90-degree bend resistance: ~14000 Ohm
- 180-degree bend resistance: ~22000 Ohm
