The Latest in IT Security

Theres no doubt that Google is becoming a full-fledged hardware company, but the latest Google X project is a lot different that tablets and smartphones — the company just announced that its building a smart contact lens. However, its not meant to be a miniaturized version of Glass — its meant 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 wearers tears. Googles hoping that itll be a less painful and invasive way to monitor glucose levels than the typical method of pricking a finger and testing blood droplets 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 imagines putting a minuscule LED light in the lens that could indicate levels dropping above or below a set threshold.
