Stuff.co.nz reports Google has announced a project to make a smart contact lens. But this gadget isn't going to be used to deliver your email straight into your skull - at least not yet. This project is working to tackle one of the biggest health problems facing the country today: diabetes.
The soft contact lens that Google's is introducing - it's still just a prototype - houses a sensor between two layers of lenses that measures the glucose levels in tears. Stuff.co.nz explains how a tiny pinhole in the lens lets tear fluid seep over the glucose monitor to get regular readings. Right now, the company said, it can get a level reading once every second. The lens also features a tiny antenna, capacitor and controller, so that the information gathered from the lens can move from your eye to a device such as a handheld monitor, where that data can be read and analyzed. It will draw its power from that device and communicate with it using a wireless technology known as RFID, says Stuff.co.nz.
