Superhydrophobic Biosensor Measures Sweat Vapors on the Body

Sweat contains biomarkers that help doctors make health diagnoses. Wearable sensors can be used to monitor a person’s perspiration rate and provide information about the skin, nervous system activity, and underlying health conditions. But not all sweat is created equal, and some cannot be measured with current sensors. A newly developed superhydrophobic biosensor could be used as a diagnostic tool to detect such types of sweat.
