Researchers at the University of California, San Diego have tested a proof-of-concept tattoo that extracts and measures glucose

Adhesive wearables hold lots of promise for fitness and health monitoring in the future. One such proof-of-concept device has been developed by nanoengineers at the Universtiy of California, San Diego: a new temporary tattoo that monitors blood glucose levels.

The flexible, easy-to-wear device extracts and measures the level of glucose in the fluid between skin cells. It was developed and tested by graduate student Amay Bandodkar and colleagues in Professor Joseph Wang’s laboratory at the NanoEngineering Department and the Center for Wearable Sensors at the Jacobs School of Engineering at UCSD. The device consists of patterned electrodes printed on temporary tattoo paper.
