    • Exemplary embodiments provide precision resistive composite members and methods for manufacturing and using them. The resistive composite member can have controllable dimensions, geometric shapes, mechanical properties and resistance values. The resistive composite member can be used for high-performance sensors or instrument probes that require, for example, high contact pressure, ultra-high frequency, and/or enable state-of-the-art digital signal transmission, characterization, or measurement. The resistive composite member can include one or more “twisted-fiber-tow” or one or more arrays of “twisted-fiber-tow” contained in a suitable non-metallic or essentially non-metallic binder material. The “twisted-fiber-tow” can further include a number of fibers that are twisted individually and/or in bundles in order to control the mechanical properties and fine-tune the resistance of the resistive composite member and thus to customize the high-performance instrument probes.
    • 示例性实施例提供精密电阻复合构件以及用于制造和使用它们的方法。 电阻复合元件可以具有可控尺寸,几何形状,机械性能和电阻值。 电阻复合构件可用于需要例如高接触压力,超高频和/或使能最先进的数字信号传输,表征或测量的高性能传感器或仪器探针。 电阻复合构件可包括一种或多种扭曲纤维丝束或一种或多种包含在合适的非金属或基本上非金属粘合剂材料中的扭曲纤维丝束阵列。 扭绞纤维束可以进一步包括多个单独地和/或成束地扭绞的纤维,以便控制机械性能并微调电阻复合构件的电阻,从而定制高性能仪器探针 。
