摘要

Radio frequency interconnects integrated into textile substrates are indispensable for high-throughput data transmission in continuous on-body monitoring and real-time personalized interventions. However, prevailing printed electronic architecture suffers from mechanical rigidity and performance instability, which compromises their reliability under complex deformations inherent to human motion. Here, we report a single-fiber buckling embroidered metafabric (SBEM) that supports spoof surface plasmonic polariton at microwave frequencies. By exploiting kirigami-inspired topological transformation and periodic buckling of a single conductive fiber, the embroidered metafabric attains robust mechanical flexibility while maintaining its highly-squeezed surface modes. Compared with conventional printed electronic textiles, the SBEM exhibits markedly superior mechanical resilience and electromagnetic (EM) stability under large deformation, ensuring reliable signal transmission across a wireless body-area sensing network. Moreover, to ensure reliable EM performance under mechanical stretching, the dispersion relations governed by the geometric parameters of the metafabric unit cell are engineered to maintain a stable operational band of signal transmission. The SBEM retains 90.3% of its transmitted power after 1000 stretch-release cycles at 10% strain, and maintains 80.5% and 88.1% of its transmitted power even under 180° twisting and 40 mm-radius bending, respectively. We further validate the potential of the SBEM for underwater radio frequency sensing. This work offers a mechanically reconfigurable and electromagnetically robust spoof surface plasmonic polariton metafabric platform for next-generation wireless body-area sensing and wearable elastronics.
