With the rapid expansion of wireless networks, the deployment and long-term maintenance of distributed microwave terminals have become increasingly challenging. To address these issues, we present a bio-inspired microwave system to constitute passive and maintenance-free wireless networks. Drawing inspiration from vertebrate skeletons and skins, we employ stimuli-responsive polymer with tunable stiffness to support and protect sensitive electromagnetic structures, and synthesize self-healable skin-like polymer for system encapsulation. Owing to the biomimetic strategy, our system combines outstanding flexibility, electromagnetic stability, structural robustness, and self-healable performance. On the other hand, to address power supply issues, our system modulates ambient electromagnetic waves to achieve long-range wireless communication, and the hybrid energy harvesting strategy allows the system to capture energy from ambient light and microwaves, thereby eliminating the need for batteries or power cables. Multidisciplinary innovation enables our system to be deployed almost anywhere and supports stable, battery-less, and maintenance-free wireless communication.
随着无线网络的迅速扩展，分布式微波终端的部署和长期维护变得越来越具有挑战性。为了解决这些问题，我们提出了一种受生物启发的微波系统，以构建无源且无需维护的无线网络。从脊椎动物的骨骼和皮肤中汲取灵感，我们采用具有可调刚度的刺激响应聚合物来支撑和保护敏感的电磁结构，并合成用于系统封装的可自愈皮肤状聚合物。由于采用了仿生策略，我们的系统兼具出色的柔韧性、电磁稳定性、结构坚固性和自愈性能。另一方面，为了解决电源问题，我们的系统调制环境电磁波以实现远程无线通信，并且混合能量收集策略使系统能够从环境光和微波中捕获能量，从而无需电池或电源线。多学科创新使我们的系统几乎可以部署在任何地方，并支持稳定、无电池且无需维护的无线通信。
