Wearable medical devices have enabled unobtrusive monitoring of vital signs and emerging biofeedback services in a pervasive manner. This article describes a wearable respiratory biofeedback system based on a generalized body sensor network (BSN) platform. The compact BSN platform was tailored for the strong requirements of overall system optimizations. A waist-worn biofeedback device was designed using the BSN. Extensive bench tests have shown that the generalized BSN worked as intended. In-situ experiments with 22 subjects indicated that the biofeedback device was discreet, easy to wear, and capable of offering wearable respiratory trainings. Pilot studies on wearable training patterns and resultant heart rate variability suggested that paced respirations at abdominal level and with identical inhaling/exhaling ratio were more appropriate for decreasing sympathetic arousal and increasing parasympathetic activities.
可穿戴医疗设备以一种普及的方式实现了对生命体征的非介入式监测和新兴的生物反馈服务。本文描述了一种基于通用体传感器网络（BSN）平台的可穿戴呼吸生物反馈系统。紧凑的 BSN 平台是根据整体系统优化的强烈需求定制的。使用 BSN 设计了腰部佩戴的生物反馈设备。广泛的台架测试表明，通用 BSN 按预期运行。对 22 名受试者的现场实验表明，该生物反馈设备隐蔽、易于佩戴，并能够提供可穿戴的呼吸训练。对可穿戴训练模式和由此产生的心率变异性的初步研究表明，在腹部水平进行有节奏的呼吸，并且吸气/呼气比相同，更适合降低交感神经兴奋，增加副交感神经活动。
