The nanomechanical resonator composed of two-dimensional materials has seen extensive investigations, but the interaction between two adjacent resonators has not called much attention. The paper reports a vibration transfer phenomenon within a graphene film covering two neighboring holes. When an electrostatic excitation was applied to one of the resonators, vibration signals were detected in both resonators but with a 90° phase difference, as measured by a microscopic laser vibrometer. The findings were validated through finite element simulations and molecular dynamics simulations. It is concluded that the occurrence of this vibration transfer phenomenon is attributed to the slip displacement of graphene film within the middle connection region. The vibration transfer phenomenon sheds light on issues such as resonator excitation, signal transfer, and modal coupling. Moreover, two orthogonal signals with a 90° phase difference hold significant value for applications across various fields, including digital communication systems.
