The rapid evolution of wearable electronics urgently requires stretchable electrodes combining mechanical compliance, high conductivity, and long‐term biocompatibility. While traditional thin‐film electrodes suffer from inadequate breathability and interfacial instability, spinning‐derived fiber architectures overcome these limitations through porous, 3D interconnected networks that enable efficient strain dissipation. Despite extensive research on conductive fibers, existing literature often lacks a systematic analysis of how spinning technologies govern structural engineering and optimize electromechanical performance. To bridge this gap, this review comprehensively examines spun stretchable electrodes—encompassing metallic, liquid metal, carbon‐based, and polymeric systems—explicitly positioning spinning technology as the vital bridge between material design and device‐level architecture. We deeply analyze the intrinsic structure‐property relationships, emphasizing interface design, shedding/detachment mitigation, and the decoupling of mechanical deformation from electrical conduction. Furthermore, we highlight advanced structural integration and representative sensing applications. Ultimately, by addressing critical challenges such as scalable manufacturing, structural durability, and system‐level integration, this review provides a holistic materials‐to‐device perspective, offering strategic guidance for the future design of high‐performance, breathable, and integrated wearable platforms.
