The concept of Wireless Sensor Networks (WSN) emerged in the last decade, with various applications proposed. It was envisioned that the ubiquitous sensing and communication devices would soon integrate into our daily life, providing information and convenience wherever and whenever we need. However, to date, we have yet to see mass adoption of such applications, mainly due to the lack of viable wireless sensing devices, as well as the fragmentation of the data storage, computing, and networking infrastructure.

Recent advances in the field of artificial intelligence, big data, and cloud computing, as well as concurrent attempts in standardization in low-power wireless mesh networking and security are paving the way for the commercialization of WSN applications. With the commercial ecosystem getting in place and infrastructures becoming mature, the challenge lies in the research and development of low-cost, miniaturized, and self-sustaining circuits and systems realizing sensing and wireless communication functionalities which are critical in the future WSN landscape.

This special issue invites researchers to present their latest original research progress and review articles summarizing the most recent developments in the field of circuits and systems related to wireless sensing.
