可穿戴医疗设备已经使得能够以普遍的方式对生命体征和新兴的生物反馈服务进行不引人注目的监测。本文介绍了一种基于广义身体传感器网络（BSN）平台的可穿戴呼吸生物反馈系统。紧凑型BSN平台专为满足整体系统优化的强烈要求而量身定制。利用生物传感器网络设计了一种腰戴式生物反馈装置。广泛的台架测试表明，广义BSN工作的预期。22名受试者的现场实验表明，生物反馈装置是谨慎的，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，腹部水平和相同的吸气/呼气比的起搏呼吸更适合于减少交感神经唤醒和增加副交感神经活动。
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.
