Google’s vision for wearable technology took another leap forward recently, when the internet search company announced it is developing a smart contact lens.
Google had to design its own tiny chips and mount them on very thin, flexible, plastic-like film. The chip and a sensor are embedded between two layers of soft contact lens material. A tiny pinhole in the lens lets tear fluid from the surface of the eye to seep into the glucose sensor. The prototypes can take a glucose level reading once every second. The sensor is so small it would appear like a speck of glitter to the wearer and it could eliminate the need for diabetics to spend a lot of time having to prick their fingers to draw blood to measure their glucose levels.
