Wearable Bioimpedance Monitoring: Viewpoint for Application in Chronic Conditions

Currently, nearly 6 in 10 US adults are suffering from at least one chronic condition. Wearable technology could help controlling the health care costs by remote monitoring and early detection of disease worsening. However, recent years, there have been disappointments wearable with respect to reliability, lack feedback, or user comfort. One promising sensor techniques for is bioimpedance, which a noninvasive, versatile sensing method that can be applied different ways extract wide range parameters. Due changes impedance caused either breathing blood flow, time-varying signals such as respiration cardiac output obtained bioimpedance. A second application area related body composition fluid status (eg, pulmonary congestion patients heart failure). Finally, bioimpedance used continuous real-time imaging during mechanical ventilation). In this viewpoint, we evaluate use conditions, focusing on current status, improvements, challenges still need tackled.
