University of California San Diego engineers have created a smartphone case that, when paired with an app, can make it easier for people with diabetes to track and record blood glucose levels on the go.
“Integrating blood glucose sensing into a smartphone would eliminate the need for patients to carry a separate device,” Patrick Mercier, professor of electrical and computer engineering at UC San Diego, said in a press release. “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.”

Diabetes affects approximately 30.3 million Americans, according to the American Diabetes Association. Another 1.5 million people will be diagnosed with diabetes a year. Blood glucose is affected by food, activity and stress and measuring helps reduce the risk of hypoglycemic and hyperglycemia.

GlucPhone is a portable glucose sensing system created by Mercier along side nanoengineering professor Joseph Wang. The device has two parts. The first is a slim 3D printed case with a permanent, reusable sensor in the corner. The second part is small, one-time use, enzyme packed pellets that attach to the sensor with a magnet. The pellets are encased in a 3D printed stylus that is attached to the side of the case.
