Special Issue Information

Dear Colleagues,

This Special Issue will focus on advances in research regarding wearable antennas and sensors, emphasizing their transformative roles in biomedical monitoring, environmental sensing, and human–machine interfaces. As technologies in miniaturization, wireless power transfer, and biocompatibility progress, wearable systems are evolving into highly sophisticated platforms that enable continuous, non-invasive data acquisition in real-world environments.

The scope of this Special Issue includes antenna designs for body-centric communications, sensor integration for monitoring physiological and environmental parameters, safety evaluations that address Specific Absorption Rate (SAR) and thermal effects, and the development of emerging materials and fabrication techniques. By addressing these areas, this Special Issue will capture both the foundational principles and state-of-the-art innovations that will define the future of wearable systems.

This topic is particularly relevant to the MDPI Sensors journal due to its strong multidisciplinary impact, bridging electromagnetics, materials science, biomedical engineering, and data analytics. Wearable technologies are pivotal to next-generation healthcare, personalized medicine, and smart environments, aligning with global priorities around digital health and sustainability. The rapid pace of progress in both academia and industry makes the field especially timely for a curated collection of high-quality contributions. By consolidating knowledge and fostering cross-disciplinary collaboration, this Special Issue will provide a platform for pioneering research and a foundation for future breakthroughs.

Topics of interest for this Special Issue include, but are not limited to, the following:

  • Wearable antennas and sensors;
  • Body-centric wireless devices;
  • Flexible and stretchable electronics;
  • Wireless power transfer for wearables;
  • Specific Absorption Rate (SAR) and thermal safety;
  • Smart textiles and e-textile integration;
  • Miniaturized biomedical wearable sensors;
  • Real-time data acquisition and telemetry;
  • On-body and off-body communications.

This study investigates the frequency-dependent electrical conductivity of electrically conductive threads (also known as e-threads), particularly focusing on their inherently lower conductivity than traditional conductors like copper. While efforts have been made to electrically characterize conductive threads in the past, most studies have focused on DC or frequencies lower than 1 GHz. Recent works have evaluated attenuation up to 6 GHz, but they do not report bulk conductivity and lack validation in the context of antenna applications. In a major step forward, this study reports a systematic way of characterizing the surface conductivity of conductive yarns, for eight different thread types, from 10 MHz to 6 GHz. Different parameters such as insertion loss, attenuation, and conductivity are reported, determining the suitability of conductive yarns at specific frequencies. The study also reports the first frequency-dependent bulk conductivity of individual conductive threads. By measuring both surface and bulk conductivity, our work provides foundational data crucial for designing textile-based antennas and sensors. The practical relevance of the proposed approach is demonstrated through simulations and measurements of a broadband log-spiral antenna and a single-turn loop antenna. Overall, this research contributes valuable insights into the integration of e-textiles in smart fabric applications, paving the way for further innovations in this evolving field. Full article
