nConductive polymers represent a unique class of functional materials that combine the electrical characteristics of metals with the mechanical flexibility of polymers. These dual properties are critical for the next generation of electro-mechanical systems, including wearable sensors, soft robotics, structural health monitoring (SHM), and biomedical actuators. However, the mechanical performance of conductive polymers under diverse stress conditions—such as elongation, cyclic loading, bending, and impact—remains a key challenge, limiting their long-term reliability and system-level integration. This review provides a comprehensive analysis of the structure–property relationships governing the electro-mechanical behavior of conductive polymers under mechanical stress. Critical parameters, including polymer backbone rigidity, molecular weight, degree of crystallinity, crosslinking density, and dopant type/concentration, are examined with respect to their influence on both electrical conductivity and mechanical resilience. The role of polymer nanocomposites, incorporating carbon nanotubes, graphene, and metal nanowires, is explored to demonstrate how hybrid material architectures can mitigate mechanical degradation and enhance electro-mechanical coupling under strain. Additionally, the review highlights advanced modeling techniques, including molecular dynamics and finite element simulations, that provide valuable insights into deformation mechanisms and inform material design. Special attention is given to emerging applications in flexible strain sensors, structural health monitoring, wearable electronics, and smart actuators, where conductive polymers must maintain stable performance under repetitive mechanical inputs. The integration of self-healing and adaptive capabilities is also discussed as a promising direction for improving device longevity. By bridging material-level insights with system-level performance, this review aims to guide the development of conductive polymer-based components for advanced electro-mechanical systems and contribute to the realization of smart, adaptive structures in real-world engineering environments.nn
