Research on creating special structures with a negative Poisson's ratio, known as auxetic metamaterials, is widely conducted for potential applications in flexible electronics, aerospace, biomedicine, and other fields. Auxiticity the phenomenon of transverse expansion that occurs when stretched longitudinally. However, conventional metamaterial tunable properties have certain limitations, mainly form limited ratio tuning range deformation. In this work, series symmetric antichiral significant effect low −5 are designed fabricated by 3D printing. Based manipulating unit parameters use shape memory polymers, metamaterials exhibit mechanical programmable behaviors. Owing to these features, demonstrated achieve excellent shape-fitting size-fitting capabilities, which followed expanding full contact any objects (due auxiticity) then contract conform their shapes memory). By integrating electromyography(EMG) electrodes, can be used self-adaptive wearable devices fit human limbs, ensure good attachment, high signal Noise Ratio (SNR), breathability collect EMG signals.
