title = "Analytical modelling of microfluidic cantilever sensor with evaporating ethanol",
abstract = "Resonating microcantilevers are increasingly used for a broad range of ultra-sensitive biochemical sensing applications wherein a shift in the resonant frequency is used to detect minute changes in the cantilever mass. An extension of this technique has been realized using integrated microfluidic cantilevers wherein the resnonace shift is due to changes in fluid mass within an internal microchannel. In this paper, we develop computational models for predicting the behavior of microfluidic microcantilever sensors and validate the models using experimental data based on the evaporation of ethanol. Two computational models are presented, a one-dimensional structural beam element model and a three-dimensional finite-element structural dynamic model. The numerically predicted increase in the resonant frequencies due to a decrease in ethanol mass correlates well with experimental data. The models enable proof-of-concept studies and the rational design of novel microfluidic microcantilever biochemical sensing systems.",
