    • A magnetic position sensor having at least one magnetic field sensor including a solidified layer of GMR nanowire carrier fluid formed on a substrate material. The solidified layer of carrier fluid has (i) discrete GMR nanowires each having a diameter of less than about 0.5 um and a length less than about 250 um; and (ii) a concentration of GMR nanowires in the dried layer between about 0.001 and about 10 percent by weight of the solution. The position sensor further includes a detection circuit capable of detecting a change in resistance of the magnetic field sensor.
    • 一种具有至少一个磁场传感器的磁性位置传感器,该磁场传感器包括形成在基底材料上的GMR纳米线载体流体的凝固层。 载体流体的固化层具有(i)离散的GMR纳米线,其各自具有小于约0.5μm的直径和小于约250μm的长度; 和(ii)干燥层中的GMR纳米线的浓度为溶液重量的约0.001%至约10%。 位置传感器还包括能够检测磁场传感器的电阻变化的检测电路。
