6 gadgets that could save your life

Jamming a computer into your eyeball may not sound like a pleasant experience, but Google (GOOG) thinks that could be a solution for diabetes sufferers. The company said earlier this year that it's testing a contact lens that measures glucose levels in tears via a tiny wireless chip.

The hope is that the device will allow patients to monitor their blood sugar levels in real time, and without having to prick their fingers and test drops of their blood throughout the day. Compared to that, the computer in the eyeball sounds positively pleasant.
