(GIST OF SCIENCE REPORTER) Wearable Sweat Sensor

Researchers from Brazil have created a wearable sweat sensor which is a skin-adherent biosensor based on pure nanocellulose fibre substrate. The natural polymer offers a breathable interface with the skin and permits sweat to travel through for further electrochemical analysis with the help of printed electrodes.
It can measure a range of metabolites and biomarkers present in sweat and monitor problems like diabetes. This wearable sensor overcomes various drawbacks caused by plastic sensors including sweat to build up, irritation etc. It can measure various biomarkers like glucose, lactic acid, potassium, and sodium. The related study is published in the journal Talanta.
