An anonymous reader writes: Last weekend, Silicon Valley VC Marc Andreessen called out "wearable computing" as a Next Big Thing. Now MC10, a three-year-old company making flexible electronics, is taking an old idea to new places. The startup is developing health sensors that conform to the human body, image sensors that curve like the retina, and stretchy solar cells (and other circuitry) that can be woven into the fabric of a tent or aircraft skin. Unlike organic or printed electronics, which tend to be inefficient, MC10 uses silicon islands linked by springy interconnects. It's still early, but the company has new backing from VCs, Reebok, and the U.S. government to develop wearable devices, mini-sensors, and portable power. Imagine a self-charging UAV with tiny cameras on board, and you can tell what the military wants out of this.
