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.
目前，近十分之六的美国成年人至少患有一种慢性病。可穿戴技术有助于通过远程监测和疾病恶化的早期检测来控制医疗保健成本。然而，近年来，可穿戴技术在可靠性、缺乏反馈或用户舒适度方面令人失望。用于慢性病可穿戴监测的一种有前景的传感技术是生物阻抗，它是一种非侵入性、多功能的传感方法，可以以不同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，利用生物阻抗可以获得诸如呼吸和心输出量等随时间变化的信号。第二个应用领域与身体成分和液体状态有关（例如，心力衰竭患者的肺充血监测）。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）。在这一观点中，我们评估可穿戴生物阻抗监测在慢性病中的应用，重点关注当前状况、近期进展以及仍需解决的挑战。
