Although many polar topological structures were discovered in the last decade, what new or enhanced properties could they endow remains poorly explored. Here we propose a design framework that integrates crystallographic orientation engineering and anisotropic strain modulation to construct high density inclined polar skyrmions with giant piezoelectricity (> 500 pC/N) in (111)-oriented PbTiO 3 /SrTiO 3 superlattices by the phase-field method. Crucially, the inclined skyrmions exhibit intrinsic field-induced strain amplification localized at their core polarization regions, effectively functioning as three-dimensional electromechanically active elements that drive the macroscopic piezoelectric enhancement in the superlattices, yielding nearly a 1000% increase compared to the PbTiO 3 single-layer film under the same orientation and strain conditions. These findings uncover a topological route to amplified piezoelectric functionality, underscoring the promise of orientation-strain design strategies in reconfigurable ferroics and advanced topotronic platforms.
