TL;DR
A non-monotonic dependence of EM absorption on source distance is revealed, with peak absorption occurring at a separation of 6 mm, which emphasizes critical role of source proximity in near-field exposure scenarios and provides useful insights for the design and safety evaluation of wireless sensor and communication devices.
The increasing use of wearable wireless devices operating in close proximity to the human body has raised the need for reliable assessment of electromagnetic exposure and associated thermal effects in biological tissue. In particular, wireless earbuds produce both electromagnetic energy absorption and device self-heati...
The widespread deployment of mobile communication technologies within the 700 – 900 MHz and 1.8 – 2.6 GHz frequency bands has raised concerns about electromagnetic wave exposure’s thermal effects on human tissues. This study investigates radiofrequency (RF) interactions with biological tissues. Use is made of Maxwell’s...
This study aims to investigate non-Fourier heat transfer in multilayer biological tissues subjected to laser irradiation and to develop a machine learning-based surrogate framework for rapid and accurate prediction of tissue temperature. A three-layer skin model consisting of the epidermis, dermis and subcut...
Electromagnetic therapy is a noninvasive technique in the field of modern biomedicine that involves the controlled application of electromagnetic (EM) fields to target desired tissue while avoiding any undesired interaction with neighboring regions. The advancements in EM-based therapies require significant knowledge a...
Background: Intra-abdominal pressure (IAP) has recently been recognized as a new vital sign in critically ill patients. Microwave reflectometry has been proposed as a potential approach for non-invasive IAP measurement. However, systematic investigation on how individual anatomical and geometric factors influence chang...
Background: With the large-scale global deployment of fifth-generation (5G) networks and the proliferation of wearable devices, electromagnetic field dosimetry faces the critical challenge of multi-scale evaluation, extending from the near-field of terminal devices to environmental exposure. Existing reviews mostly con...
