A wearable screen-printed electrochemical smartsensor with excellent selectivity for methanol quantification has been developed. This smartsensor consists of a printable sensing system modified with platinum (Pt) confined in reduced gra-phene oxide (rGO) matrix, as well as a compact electronic interface for data collection. The real-time electrochemical sig-nal from methanol could be remotely detected and transmitted to a smartphone by blue tooth. It performs good environ-mental adaptability of vapor/liquid amphibious behaviors. Owing to the uniform distribution of Pt loading on the rGO nanosheets, this sensor demonstrates high selectivity, sensitivity, stability and recoverability both in vapor and liquid during tempera-ture or humidity diversification, comparing with other resistance-based sensors. There also achieves good bending and stretching performance, and it could be a possible candidate device for the quantification of methanol in different environment.
