A new minimally invasive device, while still in development, could become a lifesaver for individuals with diabetes who experience hypoglycemia, according to researchers at the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts.

In a paper published in Nature Biomedical Engineering , Siddharth R. Krishnan, PhD, now an assistant professor of electrical engineering at Stanford University in Stanford, California, and colleagues at MIT described a wireless device implanted into diabetic mice that prevented hypoglycemia.

The implant weighs < 2 g and is only 3 cm 3 in size; it remains under the skin and releases a powdered version of glucagon automatically when a sensor detects low blood sugar.

The researchers simulated hypoglycemia in the mice, and the release of t
