Systems and methods for a flexible dynamic loop having reduced impedance are described. The flexible dynamic loop may supply current from a preamplifier to another device, such as a hard disk drive. In one embodiment, a flexible dynamic loop comprises a flexible structure having a set of wire traces. The flexible dynamic loop may also comprise a set of impedance control structures on the flexible structure and perpendicular to a bend radius of the flexible structure, wherein the set of impedance control structures change an impedance level experienced by at least some of the set of wire traces. Some of the impedance control structures may be staggered. The flexible dynamic loop may also include a cover layer formed over the set of impedance control structures, which may be patterned with perforations. The flexible dynamic loop may also include one or more flexible rails connecting some of the impedance control structures.
