MIT researchers developed light-detecting fibers that could eventually be woven into a "fabric camera." Instead of counting on a single lens, the new system would use a web of the fibers as a distributed imaging surface. Imagine a shirt where the entire back is a "camera." From MIT News:
The researchers, led by Associate Professor Yoel Fink of the Department of Materials Science and Engineering (DMSE), emphasize that while such an application and others like it are still only dreams, work is rapidly progressing on developing fabrics capable of capturing images. In a recent issue of the journal Nanoletters, the team reported what it called a "significant" advance: using such a fiber web to take a rudimentary picture of a smiley face.
"This is the first time that anybody has demonstrated that a single plane of fibers, or 'fabric,' can collect images just like a camera but without a lens," said Fink, corresponding author of the Nanoletters paper. "This work constitutes a new approach to vision and imaging."
