“…The different responses of the local and the basic modes to adsorption mass, and the effects of the local modes on the quality factor of mechanical vibration were examined. The results show that increasing the aspect ratio and pre-stressing of graphene sheets can effectively improve the quality factor of the graphene resonant mass sensor [92].…”

Graphene nano-electromechanical resonant sensors have wide application in areas such as seawater desalination, new energy, biotechnology, and aerospace due to their small size, light weight, and high sensitivity and resolution. This review first introduces the physical and chemical properties of graphene and the research progress of four preparation processes of graphene. Next, the principle prototype of graphene resonators is analyzed, and three main methods for analyzing the vibration characteristics of a graphene resonant sheet are described: molecular structural mechanics, non-local elastic theory and molecular dynamics. Then, this paper reviews research on graphene resonator preparation, discussing the working mechanism and research status of the development of graphene resonant mass sensors, pressure sensors and inertial sensors. Finally, the difficulties in developing graphene nano-electromechanical resonant sensors are outlined and the future trend of these sensors is described.

“…Simulation in the canonical NVT ensemble at the same temperature (where atomic number, volume, and temperature are kept constant). The edges of the graphene were fixed after structural relaxation and a sinusoidal velocity excitation as shown in equation (2) [10,12,42] was applied to the central part.…”

“…With the hybrid structure of graphene supported by carbon nanotubes (CNTs) being employed in resonators and proven feasible, the origami graphene structure could also be a strong candidate for resonators. Xiao et al [12] proposed a mass determination method using the first three resonance modes to avoid interference of stress fluctuations in graphene. Ye et al [13] reported on the first experimental demonstration of electrothermally tuned single-and few-layer graphene NEMS resonators operating in the high-frequency (HF) and very highfrequency bands and demonstrated a wide tuning frequency range of up to D = / f f 310%.…”

The unique mechanical properties of graphene make it an excellent candidate for resonators. We have used molecule dynamic to simulate the resonance process of graphene. The kirigami approach was introduced to improve the mass sensitivity of graphene sheets. Three geometric parameters governing the resonant frequency and mass sensitivity of Kirigami graphene NEMS were defined. The simulation results demonstrate that the closer the Kirigami defect is to the central position of the drum graphene, the higher the mass sensitivity of the graphene, showing up to about 2.2 times compared with that of pristine graphene. Simultaneously, the kirigami graphene has a higher out-of-plane amplitude and easy access to nonlinear vibrations, leading to higher mass sensitivity. Besides, the kirigami structure can restrict the diffusion of gold atoms on graphene under high initial velocity or large tension condition. It is evident that a reasonable defect design can improve the sensitivity and stability of graphene for adsorption mass.

“…[259] These measurements of resonant frequency due to attached light mass can be combined with the optical and electrical measurement methods demonstrated in Section 3 so as to further enhance the measuring efficiency. Other theoretical calculations of 2D material based mass sensors have studied the influence of temperature, [260] in-plane magnetic field, [261] layer numbers, [262] internal stress, [263] diameter to thickness ratio [264] and higher order nonlinear vibration modes. [265] The results of these theoretical calculations provide feasible suggestions for future experiments with enhanced sensitivity and reliability of mass sensors.…”

Acoustic devices play an increasingly important role in modern society for information technology and intelligent systems, and recently significant progress has been made in the development of communication, sensing, and energy transduction applications. However, conventional material systems, such as polymers, metals and silicon, show limitations to fulfill the evolving requirements for high‐performance acoustic devices of small size, low power consumption, and multifunctional capabilities. 2D materials hold the promise in overcoming the development bottleneck of acoustic devices aforementioned, given their atomic‐thin thickness, extensive surface area, superior physical properties, and remarkable layer‐stacking tunability. By suspending the 2D materials, mechanical and thermal disruption from substrate will be eliminated, which will enable the development of new classes of acoustic devices with unprecedented sensitivity and accuracy. In this review, the recent progress of acoustic devices based on suspended 2D materials and their composites, especially applications in the audio frequency, static pressure, and ultrasonic frequency range, is briefly summarized, emphasizing the advantageous properties of suspended 2D materials and related outstanding device performance. Together with the development of 2D membrane synthesis, transfer, as well as microelectromechanical fabrication process, suspended 2D materials will shed light on the next‐generation high‐performance acoustic devices.
