Recently, stretchable electronics combined with wireless technology have been crucial for realizing efficient human-machine interaction. Here, we demonstrate highly stretchable transparent wireless electronics composed of Ag nanofibers coils and functional electronic components for power transfer and information communication. Inspired by natural systems, various patterned Ag nanofibers electrodes with a net structure are fabricated via using lithography and wet etching. The device design is optimized by analyzing the quality factor and radio frequency properties of the coil, considering the effects of strain. Particularly, the wireless transmission efficiency of a five-turn coil drops by approximately only 50% at 10 MHz with the strain of 100%. Moreover, various complex functional wireless electronics are developed using near-field communication and frequency modulation technology for applications in content recognition and long-distance transmission (>1 m), respectively. In summary, the proposed device has considerable potential for applications in artificial electronic skins, human healthcare monitoring and soft robotics.
最近，可拉伸电子产品与无线技术的结合对于实现高效的人机交互至关重要。在这里，我们展示了由 Ag 纳米纤维线圈和用于功率传输和信息通信的功能电子元件组成的高拉伸透明无线电子产品。受自然系统的启发，通过使用光刻和湿法刻蚀，制造了具有网状结构的各种图案化 Ag 纳米纤维电极。通过分析线圈的品质因数和射频特性，考虑应变的影响，对器件设计进行了优化。特别是，在 10MHz 时，五匝线圈的无线传输效率在应变 100%时仅下降约 50%。此外，还使用近场通信和调频技术开发了各种复杂的功能无线电子产品，分别用于内容识别和远距离传输（>1m）。总之，所提出的器件在人造电子皮肤、人体健康监测和软机器人等应用方面具有很大的潜力。
