Painless wearable gadget can measure blood sugar, alcohol and muscle fatigue at the SAME time

A new wearable gadget that fixes to the arm can measure blood sugar and muscle fatigue at the gym and alcohol levels at the pub. Created in California, the prototype can continuously monitor three health stats – glucose, alcohol and lactate levels – either separately or simultaneously in real-time. About the size of three poker chips stacked together, it is applied to the skin painlessly through a Velcro-like patch of microscopic needles. These needles take readings from fluid under the skin and then sends the data wirelessly to a custom smartphone app. Researchers hope to commercialise the device, which could provide a single solution for diabetes patients in everyday life.
