ABSTRACT Conductive rubber, as a class of functional composites that simultaneously combine mechanical flexibility and electrical conductivity, has attracted extensive attention in flexible sensing and intelligent electronic systems. Its electromechanical coupling behavior originates from the multi‐scale structural evolution of conductive filler networks under external mechanical stimuli; however, the underlying mechanisms remain highly complex and a unified understanding is still lacking. This review systematically summarizes the material systems, conductive mechanisms, and electromechanical coupling characteristics of conductive rubber. Particular emphasis is placed on the roles and governing laws of percolation, tunneling, and contact‐resistance evolution, as well as on the evolution of conductive networks under different loading modes. On this basis, a unified multi‐mechanism electromechanical coupling framework is proposed to rationalize the nonlinear and fatigue‐related electrical responses of conductive rubber across different deformation regimes. Finally, future research directions and application prospects of conductive rubber in flexible sensing and intelligent structures are discussed.
