  The unique properties and atomic thickness of two-dimensional (2D) materials
enable smaller and better nanoelectromechanical sensors with novel
functionalities. During the last decade, many studies have successfully shown
the feasibility of using suspended membranes of 2D materials in pressure
sensors, microphones, accelerometers, and mass and gas sensors. In this review,
we explain the different sensing concepts and give an overview of the relevant
material properties, fabrication routes, and device operation principles.
Finally, we discuss sensor readout and integration methods and provide
comparisons against the state of the art to show both the challenges and
promises of 2D material-based nanoelectromechanical sensing.
