Dear Colleagues,

Future wireless environments will rely on machine-centered communications and human-to-machine interactions to enable intelligent applications to Internet-of-Things (IoT), smart healthcare, smart homes and smart cities. This necessitates a paradigm shift in wireless technologies, which enables low-power, long-distance and high-speed communication. Apart from wireless communication, there is an increasing demand for technological advancements in low-power sensors and wireless energy harvesting, which will inevitably become key elements for power-autonomous, self-sustained wireless sensing networks (WSN). According to Cisco’s report, over 80 billion smart sensors will be available on the market in the next 3 years, thus, we predict unpredictable growth in hardware/software development for low-power, long-range simultaneous wireless powering, communication and sensing.

High-efficiency antennas and rectennas, integrated wireless powering and communication circuits, as well as the low-cost integration of smart sensors, will undoubtedly play an important role in laying the foundation for power-autonomous, long-range WSN. To accommodate the need for intelligent wearables, flexible electronics in, e.g., inkjet printing antennas/circuits and additively manufactured devices, are promising way of obtaining an entirely integrated wireless powering, communication and sensing platform. There are emerging applications in a number of areas, such as millimeter-wave ubiquitous sensing and backscattering energy-autonomous sensing, human vital signal monitoring, battery-less communication and so on.

This Special Issue will focus on the cutting-edge research in academia and industry. It aims to solicit original research and review articles concerning the antenna design, circuit integration and sensing applications of low-power, long-range WSN. A particular focus will be given to the flexible electronics packaging and novel fabrication techniques of the above-mentioned elements. Potential topics include, but are not limited to, the following:

➢ Rectenna design and rectifiers for energy harvesting;

➢ Inkjet printing, 3D printing and advanced packaging of flexible antennas;

➢ Integrated circuits for joint wireless communication, energy harvesting and sensing;

➢ Flexible electronics, flexible antennas and circuits;

➢ Wearable electronics, wearable antennas and energy harvesting;

➢ Advanced fabrication and measurement technology for flexible antennas;

➢ Practical application of flexible antennas and circuits for energy harvesting.

We look forward to receiving your contributions.
