本文对微波技术在新一代可穿戴设备中的作用进行了全面而权威的综述。以人为中心的物联网（IoT）涵盖远程医疗保健，分布式传感和消费电子产品，要求将高性能可穿戴设备集成到服装中，这需要跨学科的研究工作。微波是无线网络的“互连”，它可以实现而不是仅仅连接下一代自主、可持续和可穿戴的电子产品。首先，使能技术，包括无线电力传输和RF能量收集，反向散射和无源通信，RFID和电磁传感进行了审查。然后，我们讨论了关键的集成平台，包括智能织物和电子纺织品，增材制造，印刷电子，原生柔性和有机RF半导体，以及完全集成的CMOS系统，其中强调了混合集成的机会。新兴的研究趋势，从毫米波6G，RF传感和成像，到医疗保健应用，包括神经植入物，药物输送和暴露于微波的安全性，都被重新审视和讨论，为跨学科研究提供了未来的路线图，以实现可持续和可靠的下一代可穿戴设备。
This paper presents a holistic and authoritative review of the role of microwave technologies in enabling a new generation of wearable devices. A human-centric Internet of Things (IoT) covering remote healthcare, distributed sensing, and consumer electronics, calls for high-performance wearable devices integrated into clothing, which require interdisciplinary research efforts to emerge. Microwaves, the “interconnect” of wireless networks, can enable, rather than solely connect, the next generation of autonomous, sustainable, and wearable-friendly electronics. First, enabling technologies including wireless power transmission and RF energy harvesting, backscattering and passive communication, RFID, and electromagnetic sensing are reviewed. We then discuss the key integration platforms, covering smart fabrics and electronic textiles, additive manufacturing, printed electronics, natively-flexible and organic RF semiconductors, and fully-integrated CMOS systems, where opportunities for hybrid integration are highlighted. The emerging research trends, from mmWave 6G, RF sensing and imaging, to healthcare applications including neural implants, drug delivery, and safety upon exposure to microwaves are re-visited and discussed, presenting a future roadmap for interdisciplinary research towards sustainable and reliable next-generation wearables.
