'Google's smart contact lens: what it does and how it works
Wearables may be on everyone's list as the major tech trend of the year, but Google just kicked it up to a whole new level. The company announced a project to make a smart contact lens on its official blog Thursday.
But the lens isn't going to be used to deliver your e-mail 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. The lens also features a small — really small — antenna, capacitor and controller, so that the information gathered from the lens can move from your eye to a device where that data can be read and analyzed.
According to a short explanation of the technology provided by Google, the chip and sensors are mounted on a small plastic-like film. 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.'
Since when did Google get into the medical devices business?
