Heibei University, Tianjin Hospital, Beihang University, and Penn State researchers have developed an under nose-worn, stretchable, skin-friendly, waterproof sensor to analyze breath for health monitoring. It could be use for multiple-condition screening, asthma and COPD management, or environmental hazard sensing, among other applications.
The functional gas sensor, in a moisture-resistant membrane, can operate in humid environments, such as below the nose, to monitor breath. It is skin-friendly, stretching, twisting, and conforming to the skin.
