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!
These sensors are simple to set up and great for sensing pressure, but they aren't incredibly accurate. Use them to sense if it's being squeezed, but you may not want to use it as a scale.
A simple flex sensor 4.5" in length. As the sensor is flexed, the resistance across the sensor increases. COOL! Add it to your clothes - ideal for interfacing with LilyPad Arduino!
