Abstract

In this article, the significance, clinical needs, methods and principles for continuous human body hydration level monitoring are reviewed. Maintaining hydrated is critical for physical and mental health. A long-term, continuous, convenient and accurate wearable device that can monitor the whole-body water content to provide real-time feedback is needed, especially for infants, the elderly, and people who have special needs in their tasks and occupations. Noninvasive bioimpedance measurements and microwave sensing techniques suitable for conformable wearables are summarized. Microwave probing with deeper field penetrations into the dermis layer of the skin can provide a better assessment of whole-body water content. Frequency choices for the probing signals, the need for realistic phantoms, and evaluation standards suitable for clinical uses are discussed.

期刊介绍： IEEE Antennas and Propagation Magazine actively solicits feature articles that describe engineering activities taking place in industry, government, and universities. All feature articles are subject to peer review. Emphasis is placed on providing the reader with a general understanding of either a particular subject or of the technical challenges being addressed by various organizations, as well as their capabilities to cope with these challenges. Articles presenting new results, review, tutorial, and historical articles are welcome, as are articles describing examples of good engineering. The technical field of interest of the Magazine is the same as the IEEE Antennas and Propagation Society, and includes the following: antennas, including analysis, design, development, measurement, and testing; radiation, propagation, and the interaction of electromagnetic waves with discrete and continuous media; and applications and systems pertinent to antennas, propagation, and sensing, such as applied optics, millimeter- and sub-millimeter-wave techniques, antenna signal processing and control, radio astronomy, and propagation and radiation aspects of terrestrial and space-based communication, including wireless, mobile, satellite, and telecommunications.
