Advanced Research in Wireless and Wearable Technology and Applications

Dear Colleagues,

The ongoing advancements and miniaturization of electronic circuits have enabled us to enjoy wireless and wearable devices in compact forms and small sizes, such as headsets, smart bracelets (fitness trackers), smart watches, or miniature sensors that measure either environmental parameters or physical parameters of the body. Thanks to this progress, there is a growing number of new applications and opportunities ahead of us. Additionally, progress in making advanced textile materials is another track that will lead to exciting applications in the foreseeable future in the form of smart clothing. The challenge remains to seamlessly integrate fabrics with miniature sensors, transceivers, antennas, power supplies and electric connections, all in comfortable-to-wear and practical-to-maintain products. To achieve the desired breakthrough, future research should provide efficient means of energy harvesting and wearable batteries, the seamless integration of low-profile antennas and waveguides into fabrics, small-form and low-power transceivers and the integration of various other components into a body area network. Moreover, the modeling of wireless channels for on-body and off-body communications, studying the ways that the human body interacts with electromagnetic radiation and the means for providing adequate safety measures against the excessive exposure to electromagnetic radiation should also be further addressed in the context of a larger number of high-frequency devices working in close proximity to the body over an extended period of time.

This Special Issue aims to provide the latest R&D findings in the dynamic market of wireless and wearable technology, covering analysis, circuit design and system design, integration of electronic components into a comfortably wearable product, and providing the latest findings in securing protective measures for the implementation of radio-frequency devices for the body. It invites original research contributions from the following research areas and topics close to them:

• advanced textiles and substrates;
• biomedical circuits and systems;
• energy harvesting and wearable batteries;
• wearable antennas;
• printed antennas and antennas on ultra-thin substrates;
• millimeter-wave techniques and antennas;
• terahertz antennas and applications;
• substrate integrated waveguides;
• low-power transceivers;
• wearable sensors and wireless sensor networks;
• body area networks;
• channel models for on-body communications;
• electromagnetic radiation interaction with the body.

This Special Issue intends to supplement the existing literature with a balanced selection of original research contributions addressing the development of advanced materials, components, devices and applications, in the form of theoretical and empirical studies.
