Flexible electronics are envisioned to play a major role in future wearable medical devices. An important component of this technology is flexible antennas. This paper presents a preliminary study of on-body and off-body propagation channels in Body Area
Energy harvesting (EH) is the process of capturing and storing energy from external sources or the ambient environment. The EH devices have found various emerging applications, particularly, in healthcare sector. Kinetic-based micro energy-harvesting is a
Miniaturized wearable or implantable medical sensors (or actuators) are often used in the Internet of Things (IoT) technologies in healthcare applications. However, their limited source of power is becoming a bottleneck for the pervasive use of these
Human blockage at millimeter-wave frequencies is most commonly modeled through Knife-Edge Diffraction (KED) from the edges of a vertical strip. Although extensively validated through controlled laboratory experiments, the method does not scale to realistic

Current automatic exposure notification apps primarily operate based on hard distance/time threshold guidelines (e.g., 2 m/15 min in the United States) to determine exposures due to close contacts. However, the possibility of virus transmission through
The COrona VIrus Disease – 2019 (COVID-19) pandemic has had a profound effect on the entire world. With the onset of the pandemic in 2020, also started various efforts around the world to automate the contact tracing process to increase its efficacy. Most
Miniaturized wearable or implantable medical sensors are becoming an important application area for kinetic-based micro energy-harvesters. These harvesters can generate power through the natural human body motion. The architecture based on the Coulomb
