ABSTRACT:
A sensor of force or viscosity or other attributes of a fluid comprises a mechanical resonator (10) including an element (11; 18; 123) of which the stiffness at least partially determines a modal shape of the resonance of the resonator and means (21-23) for measuring a variation of a measure of the resonance as the stiffness of said element changes. The resonator (10) may comprise two beams (10a,10b;120, 121) connected at or near one end by a yoke (12; 122) which provides a clamped condition of the resonator at said one end and connected at or near another end by said element.
