Developing patches that effectively merge intrinsic deformation characteristics of cardiac with superior tunable mechanical properties remains a crucial biomedical pursuit. Currently used traditional block-shaped or mesh patches, typically incorporating positive Poisson's ratio, often fall short matching the tissue satisfactorily, thus diminishing their repairing capability. By introducing auxeticity into this study is trying to present beneficial approach address these shortcomings patches. The featuring auxetic effect, offer unparalleled conformity complex challenges. Initially, scaffolds demonstrating effect were designed by merging chiral rotation and concave angle units, followed integrating composite hydrogel through thermally triggering, ensuring excellent biocompatibility closely mirroring heart tissue. Tensile tests revealed possessed elasticity strain capacity exceeding tissue's physiological activity. Notably, Model III showed an equivalent modulus ratio toward tissue, underscoring its outstanding potential as Cyclic tensile loading demonstrated withstood continuous heartbeats, showcasing cyclic recovery capabilities. Numerical simulations further elucidated failure mechanisms leading exploration influence on alternative design parameters, which enabled customization strength ratio. Therefore, research presents substantial for designing can emulate possess adjustable parameters.
