Inducing additional inversion symmetry breaking (ISB) can manipulate the Rashba spin splitting and thus control the SOT generation efficiency. However, previous works mainly focus on spatial ISB at the interface introduced by the heterostructure. Effective method to introduce crystal ISB and how it impacts the SOT efficiency remains elusive. Here, we report an exotic crystal ISB in SrRuO\n                    <jats:sub>3<\/jats:sub>\n                    (SRO) that can be reversibly manipulated by the ferroelectric (FE) polarization of the adjacent FE material. Scanning transmission electron microscopy reveals that this crystal ISB is a novel crystal distortion, i.e.,\n                    <jats:italic>c<\/jats:italic>\n                    \/\n                    <jats:italic>a<\/jats:italic>\n                    crystal ratio change, induced by the Ru cation's off\u2010center displacement within the electrostatic screening depth due to the FE field. By electrical harmonic measurement, we reveal that the existence of this crystal ISB can dramatically enhance the SOT efficiency in the SRO layer by more than 60%. Our work provides an alternative to design highly efficient SOT source layer, paving the way toward low\u2010power spintronics.\n
