我们解决可穿戴生物传感器（WBS）的技术和临床问题。首先，设计概念的工作分解结构，重点是环形传感器开发的作者在麻省理工学院的小组。环形传感器是一种可移动的、遥测的、连续的健康监测设备。该WBS将小型化数据采集功能与先进的光电体积描记（PPG）技术相结合，使用远上级现有指尖PPG传感器的方法采集与患者心血管状态相关的数据。特别地，环形传感器能够可靠地监测患者的心率、氧饱和度和心率变异性。技术问题，包括运动伪影，干扰血液循环，电池电源问题，得到解决，并提出有效的工程解决方案，以减轻这些问题。其次，基于环形传感器技术，探讨了WBS监测的临床潜力。
We address both technical and clinical issues of wearable biosensors (WBS). First, design concepts of a WBS are presented, with emphasis on the ring sensor developed by the author's group at MIT. The ring sensor is an ambulatory, telemetric, continuous health-monitoring device. This WBS combines miniaturized data acquisition features with advanced photoplethysmographic (PPG) techniques to acquire data related to the patient's cardiovascular state using a method that is far superior to existing fingertip PPG sensors. In particular, the ring sensor is capable of reliably monitoring a patient's heart rate, oxygen saturation, and heart rate variability. Technical issues, including motion artifact, interference with blood circulation, and battery power issues, are addressed, and effective engineering solutions to alleviate these problems are presented. Second, based on the ring sensor technology the clinical potentials of WBS monitoring are addressed.
