Tensegrity　metamaterials　are　considered　superior　to　many　traditional　materials　in　engineering　due　to　their　exceptional　variable　stiffness,　adaptive　load-bearing　capabilities,　and　adjustable　morphing　properties.　This　paper　presents　a　novel　negative　Poisson’s　ratio　tensegrity　metamaterial　featuring　a　substructure　composed　of　a　D-bar　tensegrity　structure　and　a　rotating　double-square　negative　Poisson’s　ratio　structure.　Firstly,　we　establish　the　geometric　model　of　the　D-bar　tensegrity　structure　and　determine　the　pretension　relationships　among　its　tension　elements.　We　then　describe　the　composition　of　the　tensegrity　metamaterials　and　their　performance　metrics.　The　stress-strain　behavior　of　tension　elements　is　characterized　through　tensile　tests.　Further　experiments　explore　the　effects　of　structural　angle　and　pretension　on　the　compressive　load-displacement　characteristics　of　the　structure.　Then,　the　effect　of　the　structural　angle　of　tensegrity　metamaterial　substructures　on　energy　absorption　is　analyzed.　Additionally,　the　impact　resistance　of　tensegrity　metamaterials　with　negative　Poisson　ratios　shows　significant　compressive　and　impact　durability.　Their　potential　for　enhancing　drone　protection　and　environmental　adaptability　is　also　demonstrated.　©　2025　IOP　Publishing　Ltd.　All　rights,　including　for　text　and　data　mining,　AI　training,　and　similar　technologies,　are　reserved.
