本文报道了一种基于自激耦合微悬臂梁第一模态振荡振幅比相对变化的超灵敏质量检测方法。本文提出并论证的方法利用宏观悬臂梁可以高精度地测量物体引起的特征态位移，而不受测量环境的粘性阻尼效应的影响。在这项研究中，我们将这种方法用于小质量测量，我们建立了自激耦合微悬臂梁，我们已经实现了非常小质量（约1ng）的测量，误差为1%。(C) 2015 AIP出版有限责任公司
This paper reports ultrasensitive mass detection based on the relative change in the amplitude ratio of the first mode oscillation using self-excited coupled microcantilevers. The method proposed and demonstrated using the macrocantilevers in the previous study can measure eigenstate shifts caused by objects with high accuracy without being affected by the viscous damping effect of measurement environments. In this study, moving towards the use of this method for small mass measurements, we established the self-excited coupled microcantilevers and we have achieved in measurements of very small mass (about 1 ng) with 1% order of error.
