磁软，磁致伸缩金属玻璃带被用作原位远程查询粘度传感器。当浸入液体中时，带状传感器的谐振频率的变化被示出为与液体粘度和密度乘积的平方根相关。一个弹性波模型，该模型描述了作为作用在传感器表面上的摩擦力的函数的传感器响应。
Magnetically soft, magnetostrictive metallic glass ribbons are used as in-situ remote query viscosity sensors. When immersed in a liquid, changes in the resonant frequency of the ribbon-like sensors are shown to correlate with the square root of the liquid viscosity and density product. An elastic wave model is presented that describes the sensor response as a function of the frictional forces acting upon the sensor surface.
