Abstract：
Currently, nearly 6 in 10 US adults are suffering from at least one chronic condition. Wearable technology could help in controlling the health care costs by remote monitoring and early detection of disease worsening. However, in recent years, there have been disappointments in wearable technology with respect to reliability, lack of feedback, or lack of user comfort. One of the promising sensor techniques for wearable monitoring of chronic disease is bioimpedance, which is a noninvasive, versatile sensing method that can be applied in different ways to extract a wide range of health care parameters. Due to the changes in impedance caused by either breathing or blood flow, time-varying signals such as respiration and cardiac output can be obtained with bioimpedance. A second application area is related to body composition and fluid status (eg, pulmonary congestion monitoring in patients with heart failure). Finally, bioimpedance can be used for continuous and real-time imaging (eg, during mechanical ventilation). In this viewpoint, we evaluate the use of wearable bioimpedance monitoring for application in chronic conditions, focusing on the current status, recent improvements, and challenges that still need to be tackled.
摘要：
目前,近十分之六的美国成年人患有至少一种慢性疾病。可穿戴技术可以通过远程监控和早期发现疾病恶化来帮助控制医疗保健成本。然而,近年来,可穿戴技术在可靠性方面一直令人失望，缺乏反馈,或缺乏用户舒适度。生物阻抗是用于慢性疾病可穿戴监测的有前途的传感器技术之一，这是一种非侵入性的，通用的传感方法，可以以不同的方式应用，以提取广泛的医疗保健参数。由于呼吸或血流引起的阻抗变化，例如呼吸和心输出量的时变信号可以通过生物阻抗获得。第二个应用领域与身体成分和液体状态有关（例如，心力衰竭患者的肺淤血监测)。最后,生物阻抗可用于连续和实时成像(例如，在机械通气期间)。在这个观点中,我们评估了可穿戴生物阻抗监测在慢性病中的应用，着眼于现状，最近的改进，和仍然需要解决的挑战。
