Google is developing contact lenses with embedded electronics that’s built to measure glucose levels in tears using a tiny wireless chip and miniaturized glucose sensor that are embedded between two layers of soft contact lens material.Now they are testing prototypes that can generate a reading once per second and also investigating the potential for this to serve as an early warning for the wearer.
So that it will exploring integrating tiny LED lights that could light up to indicate that glucose levels have crossed above or below certain thresholds.
Google spokesperson said, Google has not shared any details on the availability of the contact lens. "We're in discussions with the FDA (the US government that regulates health products), but there's still a lot more work to do to turn this technology into a system that people can use."
Google CEO Larry Page said in an interview that his company was looking to fundamentally change the world. "We have all this money, we have all these people, why aren't we doing more stuff? I feel like there are all these opportunities in the world to use technology to make people's lives better.
At Google we're attacking maybe 0.1 percent of that space. And all the tech companies combined are only at like 1 percent. That means there's 99 per cent virgin territory. If you're not doing some things that are crazy, then you're doing the wrong things".
One drawback both the Sensimed and Google designs have in common is that they use conventional rigid and opaque wires and electronic components. Last year researchers in Korea, in a collaboration involving Samsung, integrated a working LED built from novel, transparent and flexible nanomaterials into an off-the-shelf contact lens
