Non-invasive tear sensor continuously monitors glucose

Noviosense is a flexible sensor glucose monitor, worn in a lower eyelid. The wireless, battery-free wearable tracks glucose levels in tears, and continuously sends measurements to one’s phone.

One of three electrodes is coated with an immobilized enzyme, which converts glucose into gluconic acid, leaving the co-enzyme FAD reduced to FADH. An  oxygen molecule oxidizes the co-factor and produces a short lived molecule of hydrogen peroxide, that is converted on the electrode surface to water. This results in an electric current, measured using the other two electrodes. The electrical signal is then converted into a radio frequency signal, transmitted via antenna.

It is possible to connect the sensor to an insulin pump, creating a closed loop system.
