Millions of people with diabetes track their glucose levels daily using finger-stick devices that draw and analyze their blood. But what if they could monitor it with just a sweat sensor?
That’s the idea behind new research from Binghamton University, State University of New York that could revolutionize diabetes management by eliminating the pain and hassle.
Adapting the knowledge that Professor Seokheun “Sean” Choi’s Bioelectronics and Microsystems Lab has gained about biobatteries over the past 15 years, the new paper-based biosensor system uses Bacillus subtilis bacterial spores that germinate in response to glucose in potassium-rich bodily fluids, such as sweat. The amount of power generated would determine the glucose level…
