Multifunctional devices based on SnO 2 @rGO-coated fibers for human motion monitoring, ethanol detection, and photo response.

In this study, we developed a multifunctional device based on SnO2 @rGO-coated fibers utilizing plasma treatment, dip coating, and microwave irradiation in sequence, and finally realized highly sensitive human motion monitoring, relatively good ethanol detection, and an obvious photo response. Moreover, the high level of comfort and compactness derived from highly elastic and comfortable fabrics contributes to the long-term availability and test accuracy. As an attempt at multifunctional integration of smart clothing, this work provides an attractive and relatively practical research direction.
