Last week Google announced that it’s building a smart contact lens. But it’s more of a sensor than any replacement for Google Glass, explains The Verge. It is expected to help diabetes patients keep track of their glucose levels.
Inside the lens is a miniaturized wireless chip and glucose monitor that will measure the glucose levels of the wearer’s tears.
Today, monitoring glucose levels typically means pricking a finger multiple times a day. Ideally, the sensor would be able to generate a reading once per second, and Google wants it to act as an early warning device for when glucose levels start dropping. The company would put a LED light in the lens that indicates levels dropping above or below a set threshold.
Co-creator Babek Parviz — back in 2009, Parviz showed Wired a connected contact lens meant to measure vital signs. Microsoft and the University of Washington worked on a similar project back in 2011. Both Parviz and fellow co-founder Brian Otis were at the University of Washington and contributed to that project, as well.
