Picture of Felted Crochet Stretch Sensor
Sensors come in many forms, you can buy them already manufactured, or make them yourself. 

The latter is my favorite for many reasons. This sensor is meant to be integrated in to wearable technology projects as an alternative to buying manufactured sensors which are made of rubber, metals, plastics and ceramics. My experience with a manufactured stretch sensor hasn't been good. It is one made of rubber with crimped metal hooks at each end. It broke easily and did not hold any properties found in materials that a wearable tech piece would mainly be constructed of; fabrics, thread and so forth. You can buy this conductive rubber in any length, but still, rubber isn't always the material you want for a project.

I've been experimenting with different ways of making soft sensors, particularly ones that utilize felting techniques. >>huge felt dork<<

This sensor is crocheted in a tube, it can be crocheted in a strip and other shapes. I myself have not tried these yet, but this is why I am sharing the technique!

This technique is a starting point and meant to be ran with.
Use this for any project you see it being applicable towards and please post them when you can, I would love to see what people come up with!

I'm so sorry to get to this so late in the game... but I would like to answer teaellen 2003 finally!
A sensor is a device that you can use to translate a physical action into an electrical signal. You can use sensors in circuits to gather data on in input and apply that data to any output you can think of given what tools you are using. Examples can range from musical controllers to assistive technology devices.

This sensor is a stretch sensor, it's electrical resistance lessens once the ends are pulled and stretched. A range is created by interacting with it, which can be read by a micro controller or computer and processed in many ways. You can also achieve low resistance by scrunching it up.
sorry but what exactly is a stretch sensor?
Very well done!

Spool knitting looks like it would accomplish the same thing....only faster!

ah yes... i feel very comfortable with the crochet hook in my hand, but you can definitely find tools to circular knit for you!
