Glucose-monitoring smartphone case

FacebooktwitterlinkedinFacebooktwitterlinkedin

GPhone, developed by UCSD’s Joe Wang and Patrick Mercier, is a  smartphone case and accompanying app that records and tracks glucose readings. It is 3D-printed and has a permanent, reusable sensor on its corner. Enzyme pellets magnetically attach to the sensor, and are stored in a 3D stylus on the side.

Users dispense a pellet from the stylus onto a bare strip on the case, activating the sensor.  A drop of blood is then put on the sensor strip.  Results are displayed on the screen, and the pellet is then discarded.

The next step is to integrate glucose sensing directly into the smartphone.  This is now in the proof of concept stage.
