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.
