## Description

- description: Graphene is a key material for gas sensing applications owing to its
    high specific surface area and vast chemical modification potential. To fully
    utilize the potential of graphene, a sensing platform independent of conductive
    properties is required. In this study, we employed membrane-type surface stress
    sensors (MSS)—A kind of nanomechanical sensor operated in the static mode—As a
    sensing platform and utilized graphene oxide (GO) as a gas sensing material. MSS
    detect surface stress caused by gas sorption; therefore, chemically modified graphene
    with low conductivity can be utilized as a gas sensing material. We evaluated
    the sensing performance of a GO-coated MSS by measuring its responses to five
    gases. We demonstrated with the GO-coated MSS the feasibility of GO as a gas sensing
    material for static mode nanomechanical sensors and revealed its high selectivity
    to water vapor. Moreover, we investigated the sensing mechanism of the GO-coated
    MSS by comparing it with the sensing performance of MSS coated with reduced graphene
    oxide and graphite powder and deduced key factors for sensitivity and selectivity.
    Considering the high sensitivity of the GO-coated MSS and the compact measurement
    system that MSS can realize, the present study provides a new perspective on the
    sensing applications of graphene.
