Diabetics' wearable sensor seeks sugar in sweat

In order to monitor their blood glucose levels, diabetics typically have to perform finger-prick blood tests as often as several times a day. Thanks to research being conducted by scientists from the University of Texas at Dallas, however, a non-invasive alternative may be on the way. Led by Dr. Shalini Prasad, a team at the university is creating an electrochemical biosensor that continuously measures glucose in the wearer's sweat.
