“…It utilizes a geometric shape that can be adjusted in three-dimensional space, achieving a lower driving voltage and enhanced RF performance, surpassing conventional flat cantilever switches. However, compared to existing designs [20,70], the downside of this topology is the longer switching time, likely due to its relatively greater length.…”

“…The manufactured switch achieves lower driving voltage with fewer manufacturing steps, as shown in Figure 3a. Traditional MEMS switches require a trade-off between RF performance and driving voltage [20]. Enhancing RF performance, such as by increasing the air gap to reduce insertion loss [69], typically results in an increase in driving voltage.…”

Nano-switch structures are important control elements in nanoelectromechanical systems and have potential applications in future nanodevices. This paper analyzes the effects of surface effects, geometric nonlinearity, electrostatic forces, and intermolecular forces on the nonlinear bending behavior and adhesion stability of nano-switches. Based on the Von Karman geometric nonlinearity theory, four types of boundary conditions for the nano-switch structure were specifically calculated. The results show that surface effects have a significant impact on the nonlinear bending and adhesion stability of nano-switches. Surface effects increase the adhesion voltage of the nano-switch and decrease its adhesion displacement, and as the size of the nano-switch structure increases, the impact of surface effects decreases. A comparative analysis of the linear theory and the nonlinear theory results shows that the adhesion voltage predicted by the linear theory is smaller than that predicted by the nonlinear theory. The effect of geometric nonlinearity increases as the size of the nano-switch structure increases, as the distance between the electrodes increases, and as the aspect ratio of the nano-switch structure increases. These findings provide theoretical support and reference for the design and use of future nanodevices and nanoelectromechanical systems.
