Nanoengineers at the University of California have tested a temporary tattoo that both extracts and measures the level of glucose in the fluid in between skin cells. This first-ever example of the flexible, easy-to-wear device could be a promising step forward in noninvasive glucose testing for patients with diabetes.  The sensor was developed and tested at UC San Diego. This proof-of-concept tattoo could pave the … Continue reading Electronic skin glucose monitor successful in proof-of-concept studies.
