Researchers in the US have developed a wearable monitor that could be used to monitor metabolic diseases through gases released from a person’s skin.

It’s a spin on the use of monitors that detect chemicals in sweat using electrical signals and has the key advantage that it does not need substantial amounts of sweat to get a reading, according to the team from Ohio State University.

So far, the result of their work is a prototype of a non-invasive, wearable biosensor that continuously detects gaseous acetone that ambiently comes out of the skin and is a biomarker for metabolic diseases like diabetes and heart disease.

Volatile organic compounds like acetone can be measured using breathalyser devices, but these require active...
