Developed by researchers at Columbia University, the camera can produce an image each second, indefinitely, of a well-lit indoor scene. It does not require a wall plug or battery. "Digital imaging is expected to enable many emerging fields including wearable devices, sensor networks, smart environments, personalized medicine and the Internet of Things," said Columbia University professor Shree K. Nayar. "A camera that can function as an...Read full article
