Nanomechanical sensors have gained significant attention as powerful tools for various applications. In the static mode operation, sensing signals are obtained by a concentration-dependent sorption-induced mechanical deformation. The materials coated on the nanomechanical sensors often exhibit viscoelastic nature, and hence the dynamic response of nanomechanical sensing reflects the sorption kinetics with viscoelastic stress relaxation. In this study, we have derived an analytical solution based on sorption kinetics along with three-parameter solid model, which is applicable to multistep injection/purge cycles.
