Abstract

Understanding of the fluid-structure interaction between a mechanical resonator and a surrounding fluid is key for understanding and predicting the performance of MEMS fluid property sensors. Here, we present a novel method for modelling the fluid-structure interaction between a viscous fluid and vibra-tional eigenmodes of a plate-like MEMS resonator. The elastic dynamics of the MEMS resonator nu-merically determined by a finite element method while the fluid flow is obtained from a boundary integral formulation. With this method we compute the spectral response of MEMS plate resonators in fluids.
