To track their blood sugar levels, patients with diabetes typically prick their fingers at least three times a day and feed blood samples into glucometers. It's a tedious and sometimes painful process, and a patient will often need to run a second test due to "insufficient blood" in the first sample. Now, researchers at Baylor University, in Waco, TX, have engineered a thumb-pad sensor that measures glucose levels via electromagnetic waves--no finger pricking required. More...
