The new biosensor, which is designed to measure blood glucose when attached to the skinXUE FENG & YIHAO CHEN, TSINGHUA UNIVERSITYDeveloping noninvasive methods of glucose monitoring is challenging, but researchers have designed a new biosensor with high measurement accuracy that can be placed directly on the skin. The device integrates a battery-powered electrochemical channel that transports intravascular blood glucose to the skin surface, and an ultrathin, nanostructured biosensor absorbs and measures the glucose.

In a human clinical trial, the measurements taken from the new sensor showed a high correlation with clinically measured blood glucose levels.
