Imagine that instead of carrying a camera in your jacket pocket, your entire jacket was the camera. That is the promise of a new type of light-detecting fibers developed by researchers at MIT. The team from the Institute's Department of Materials Science and Engineering (DMSE) has developed light-detecting fibers that, when woven into a web, act as a flexible “camera”. Fabric made from these fibers could be joined to a computer to create a large, foldable telescope or made into a soldier’s uniform to provide greater situational awareness.
