In this video, Shree K. Nayar, T.C. Chang Professor of Computer Science at Columbia Engineering, takes us to the Computer Vision Laboratory to demo the self-powered video camera.
Nayar, working with research engineer Daniel Sims BS’14 and consultant Mikhail Fridberg of ADSP Consulting, designed an image sensor that harvests incident light into electric power. This breakthrough technology enables a camera to run without an external power supply. The goal: a camera that can function as an untethered device for digital imaging in emerging fields such as wearables, the internet of things, and personalized medicine.
