Knitted sensors control a lamp, a fan, and a lemon juicer, via Wired:

We control most of our gadgets through screens and buttons. And while these interfaces get the job done, they can lack a certain warmth and humanness. A new project from Royal College of Art student Yen Chen Chang explores what happens when you replace glass, metal and plastic with textile control mechanisms. The result? A totally new way to interact with our everyday devices.

Using conductive yarn made from 80 percent polyester and 20 percent stainless steel (similar to the textile used in smartphone gloves), Chang knit and crocheted a series of objects that control devices by pulling, squeezing and stroking. When manipulated, the overlap of the metal fiber causes the textile to change conductivity which is then measured by an Arduino and communicated to the gadgets.
