In this article, the pull-in instability and dynamic characteristics of electrostatically actuated suspended microchannel resonators are studied.A theoretical model is presented to describe the pull-in effect of suspended microchannel resonators by Hopper considering the electrostatic field and the internal fluid.The results indicate that the syste
