| contents | Bioimpedance is an extensively studied non-invasive technique with diverse applications in biomedicine. This comprehensive review delves into the foundational concepts, technical intricacies, and practical implementations of bioimpedance. It elucidates the underlying principles governing bioimpedance measurements, including the relevant physics equations employed for estimating body fluid levels. Moreover, a thorough examination of the prevalent single-chip analog front end (AFE) available in the market, such as AD5933, MAX30001, AD5940, and AFE4300, is conducted, shedding light on their specifications and functionalities. The review focuses on using bioimpedance to assess thoracic impedance for heart failure detection by utilizing the relation between lung water and heart failure. Traditional techniques are compared with bioimpedance-based methods, demonstrating the latter's efficacy as a non-invasive tool for cardiac evaluation. In addition, the review addresses the technical limitations and challenges associated with bioimpedance. Pertinent issues such as contact impedance, motion artifacts, calibration, and validation regarding their impact on measurement precision and dependability are thoroughly examined. The review also explores strategies and advancements in using artificial intelligence to mitigate these challenges. |
