wo researchers at the University have developed a sensor material out of hydrogel that monitors blood glucose levels continuously. In other words, the sensor can evaluate fluctuating levels of glucose in the bloodstream in a linear fashion, instead of testing for it at different points in time. The developed sensor material is very thin — only  micrometers thick — and made of the same consistency as tofu. The researchers, Professor Paul Braun and materials science and engineering graduate student, Chunjie Zhang, said this inexpensive material has the potential to help two main groups of people: Intensive


Care Unit patients who experience glucose fluctuation after surgery or traumatic injury and diabetics looking to monitor their blood sugar levels continuously. For Mary O’Donnell, freshman in  who was diagnosed with diabetes at the age of , this sensor material could be beneficial if developed into an efficient monitoring device. O’Donnell said that when she was first diagnosed, she was very good at remembering to test her blood sugar levels throughout the day, but once middle school came around, she tended to forget more. When she used a continuous glucose-monitoring
