Columbia University researchers have created a self-powered video camera featuring a sensor that both captures images and powers the device. Although it can only record low-resolution 30x40 pixel images at 1fps, the photodiodes on the camera's sensor can switch between being photoconductive, and photovoltaic. In the latter mode - given enough light - the photodiodes supply enough power to a built-in supercapacitor to keep the camera operating indefinitely. Click through for more information
