Google Develops Smart Contact Lens that Measures Glucose Levels

Jan 21, 2014

To make the 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, Google said.
