“…The arrays are formed as customized geometrical layouts and can be distinguished by an automotive radar. With the continuous development of mmWave backscatter technology [160], [181], we believe that there will be more mmWave sensing works combined with backscatter technology adapting to various sensing tasks.…”

With the rapid development of the Internet of Things (IoT) and the rise of 5G communication networks and automatic driving, millimeter wave (mmWave) sensing is emerging and starts impacting our life and workspace. mmWave sensing can sense humans and objects in a contactless way, providing fine-grained sensing ability. In the past few years, many mmWave sensing techniques have been proposed and applied in various human sensing applications (e.g., human localization, gesture recognition, and vital monitoring). We discover the need of a comprehensive survey to summarize the technology, platforms and applications of mmWave-based human sensing. In this survey, we first present the mmWave hardware platforms and some key techniques of mmWave sensing. We then provide a comprehensive review of existing mmWave-based human sensing works. Specifically, we divide existing works into four categories according to the sensing granularity: human tracking and localization, motion recognition, biometric measurement and human imaging. Finally, we discuss the potential research challenges and present future directions in this area.

Backscatter communication, an emerging ultra-low-power wireless communication paradigm, has been studied as a promising solution for wireless communications in some Internet-of-Things (IoT) applications. The required ubiquitous data transmission in the IoT world is demanding information security. Different from mathematical encryption at higher protocol layers, the directional modulation (DM) technology can provide physicallayer wireless security, which does not require digital and computation resources that are otherwise scarce in low-power IoT devices. In this paper, a synthesis-free Van-Atta backscatter array is constructed and studied. The authors show that a Van-Atta array can be made to project orthogonal interference upon the backscattered signals in the radio frequency domain. The design details of the Van-Atta DM array are elaborated, and its efficacy is validated via bit error rate simulations.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
