SAN DIEGO – Engineers at the University of California San Diego have developed a smartphone case and mobile app that will make it easier for patients to record and track their blood glucose readings.
“Integrating blood glucose sensing into a smartphone would eliminate the need for patients to carry a separate device,” said Patrick Mercier, a professor of electrical and computer engineering at UC San Diego, in a statement. “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.”
The device, called GPhone, is a new proof-of-concept portable glucose sensing system developed by Mercier, director, and Joseph Wang, co-director, of the Center for Wearable Sensors at UC San Diego, and their colleagues at the UC San Diego Jacobs School of Engineering. The team published their work recently in the publication, Biosensors and Bioelectronics.
The GPhone has two main parts: one is a slim, 3D printed case that fits over a smartphone and has a permanent, reusable sensor on one corner; the second part consists of small, one-time use, enzyme-packed pellets that magnetically attach to the sensor. The pellets are housed inside a 3D printed stylus attached to the side of the smartphone case.
“This system is versatile and can be easily modified to detect other substances for use in health care, environmental and defense applications,” Wang said, in a statement.
The system stores a considerable amount of data so that users can track their readings over long time periods.
