In this contribution, miniaturized U-shaped resonators used for viscosity and mass density sensing are presented. These devices were especially designed to reduce and overcome spurious instabilities, which were observed in previous sensor designs. Four basic sensor designs are presented and their sensitivities to viscosity and mass density are examined. The particular setups are discussed in their working principle, accuracy, stability and repeatability. First measurements are shown and the theory necessary to relate the measured data to viscosity and mass density is outlined.
