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.
As part of the School’s 150th anniversary closing celebration, faculty duos showcase 15 pairs of Columbia Engineering's technology innovations -- past and present -- in three minute presentations. Each group is introduced by Professor Andreas Hielscher, Professor of Biomedical Engineering, Electrical Engineering, and Radiology.
“Be it Hollerith’s inventions of a tabulating machine and punch cards that advanced counting and computing (including the foundation of IBM), Elmer Gaden’s work on mass production of antibiotics, William Parsons construction of the first New York City subway line (No. 1 Broadway Line), or Edwin Howard Armstrong’s invention of the FM radio—we all are still affected today by their work performed over 60 years ago.” Professor Andreas Hielscher
