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).
Connector is 0.1" spaced and bread board friendly. Check datasheet for full specifications.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

Although their readings to fluctuate and are sometimes inconsistent, they work how they are implemented. They are pretty flimsy and you can accidentally break the pins when you try to insert them on a breadboard. Other than that, with proper care and caution, they will provide you with the right readings for your projects. :)
This sensor is amazing, definitely helped with my door security project, though the connection it has with the M/F Arduino jumper cables is quite poor. I eventually just took two alligator clips and attached them to male jumpers then to the flex sensor, which is not ideal. Other than that it's great!
I am currently buried alive in another project at the moment, but I am SURE this will do the job just fine. It is "hush-hush" though...N.D.A. you understand. This is going to be fun!
The Sensor arrived fast and in great shape. I couldnt help myself and hooked it up to bet some base lines. Perfect for the application I ordered it for. Thank you for supplying it such a great price. I think I will buy MORE! I know I will.....I'm off to my shopping cart!
I've been using them for years, really interesting sensors for different applications. Watch your iron's temperature if you solder them (advised). The thin contacts part flexes very well but adding some soft wires will allow you to keep that part safe.
It is right price for this size flex sensor!!!
They work perfectly and they're quite resistant Thanks so much, Sparkfun!
Moderate flexing results in break between pins and sensor. Tried laminating the sensor to provide structural integrity, protect pins. Seems to work OK. Also, instead of pins why not provide solderless jumper plugs?
These work great to control servos for our robotic prosthetic project in my biotech engineering class. I added the SparkFun blue quick connection clip to each sensor and shrink-wrapped wires to the clip to create an easier connection for students. Students then sewed the sensors onto three fingers of some cheap cloth white gloves and put a second glove over the first to keep them in place. These sensors are very responsive and act exactly as I would have hoped.
