Smartphone case delivers blood glucose readings in one device

Engineers have developed a smartphone case and app that could make it easier for diabetics to record and track their blood glucose readings.

The advance by engineers at the University of California San Diego integrates blood glucose sensing into a smartphone and eliminates the need for patients to carry a separate device

"An added benefit is the ability to autonomously store, process and send blood glucose readings from the phone to a care provider or cloud service.” said Patrick Mercier, a professor of electrical and computer engineering at UC San Diego.

Dubbed GPhone, the device is a new proof-of-concept portable glucose sensing system developed by Patrick Mercier, nanoengineering professor Joseph Wang, and their colleagues at the UC San Diego Jacobs School of Engineering. Wang and Mercier are the director and co-director, respectively, of the Center for Wearable Sensors at UC San Diego. Their team published the work in Biosensors and Bioelectronics.
