A resonant sensor for a fluid%26apos;s viscosity and mass density, employing an out-of-plane vibrating U-shaped tungsten wire is presented. The motivation for such a design is based on four major aspects, which are: operation in the low kilohertz range, circular cross-section of the resonator, electrodynamic actuation and read-out by means of Lorentz forces and low cross-sensitivity of the device%26apos;s resonance frequency to temperature. The setup is described in detail, an analytical model is presented and results from experiments using acetone-isopropanol and DI-water-glycerol solutions are discussed to show the sensor%26apos;s performance.
