Giant moisture responsiveness of VS 2 ultrathin nanosheets for novel touchless positioning interface

Abstract

Utilizing a thin film of VS 2 ultrathin nanosheets with giant and fast moisture responsiveness, a brand-new model of moisture-based positioning interface is put forward here, by which not only the 2D position information of finger tips can be acquired, but also the relative height can be detected as the third dimensionality, representing a promising platform for advanced man-machine interactive systems.
