This is a simple flex sensor 2.2" in length. As the sensor is flexed, the resistance across the sensor increases. Made by Spectra Symbol; they claim these sensors were used in the original Nintendo Power Glove.
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 breadboard friendly. Check the datasheet for full specifications.
Note: You must add strain relief between the connector and the plastic backing or it will break if you bend it too much. The sensor is designed to be placed in a final product where it would be secured at the tab by the product's casing. Thus, for prototyping use, you'll need to apply something else to hold it together.
