A conductive interconnect structure comprises a polymeric substrate (e.g., a thermoplastic) and a plurality of compliant conductive microstructures (e.g., conductive carbon nanofibers) embedded in the polymeric substrate. The microstructures can be arranged linearly or in a grid pattern. In response to heating, the polymeric substrate transitions from an unshrunk state to a shrunken state to move the microstructures closer together, thereby increasing an interconnect density of the compliant conductive microstructures. Thus, the gap or pitch between adjacent microstructures is reduced in response to heat-induced shrinkage of the polymeric substrate to generate finely-pitched microstructures that are densely pitched, thereby increasing the current-carrying capacity of the microstructures. The polymeric material can be heated to conform or form-fit to planar and non-planar surfaces/geometries, and can be selectively heated at various portions to tailor or customize the interconnect density of the microstructures at selected portions. Associated electrical conducting assemblies and methods are provided.

A conductive fabric includes a fabric with one or more electrically conductive wire braids woven into the fabric. The one or more wire braids are woven into the fabric such that one or more portions of each wire braid are exposed at one or more surfaces of the fabric, the exposed portions of the wire braid forming connection pads. Each connection pad provides an electrical connection point for attachment to a complementary electrical connection point on an electronic component, such as a bond pad, solder bump, or connection lead. A single wire braid can be used to electrically interconnect multiple electronic components. Multiple wire braids can be arranged, with appropriate spacing and alignment of exposed portions, to electrically interconnect multiple electronic components with multiple electrical interconnects between one or more electronic components. Each electrically conductive wire braid includes a plurality of individual electrically conductive wires braided together.
