Wearable sensor checks blood alcohol content using sweat
Device shows how sweat could be used as a non-invasive source of biochemical information
Sweat alcohol levels correlate with blood alcohol levels, new research confirms. The findings come from a study by US researchers who have made a wearable device that stimulates sweat production and measures its ethanol concentration every 25 seconds. The system could be developed to track important analytes like hormones, or pharmaceuticals, to tell users how drugs are metabolising in their body in real time.
