This episode explores E Ink, the MIT-born technology that helped transform digital reading.

By moving electrically charged particles inside microscopic capsules, E Ink creates a paper-like display that uses power primarily when the image changes. But the bigger story goes beyond the technology itself: it demonstrates what becomes possible when university research moves from discovery to commercialization—and ultimately into people’s everyday lives.

From a laboratory concept to thousands of books on a single handheld device, E Ink is a compelling example of innovation at scale.
