Currently considerable research is being directed toward developing methodologies for controlling emotion or releasing stress. An applied branch of the basic field of psychophysiology, known as biofeedback, has been developed to fulfill clinical and non-clinical needs related to such control. Wearable medical devices have permitted unobtrusive monitoring of vital signs and emerging biofeedback services in a pervasive manner. With the global recession, unemployment has become one of the most serious social problems; therefore, the combination of biofeedback techniques with wearable technology for stress management of unemployed population is undoubtedly meaningful. This article describes a wearable biofeedback system based on combining integrated multi-biosensor platform with resonance frequency training (RFT) biofeedback strategy for stress management of unemployed population. Compared to commercial system, in situ experiments with multiple subjects indicated that our biofeedback system was discreet, easy to wear, and capable of offering ambulatory RFT biofeedback.Moreover, the comparative studies on the altered autonomic nervous system (ANS) modulation before and after three week RFT biofeedback training was performed in unemployed population with the aid of our wearable biofeedback system. The achieved results suggested that RFT biofeedback in combination with wearable technology was capable of significantly increasingoverall HRV, which indicated by decreasing sympathetic activities, increasing parasympathetic activities, and increasing ANS synchronization. After 3-week RFT-based respiration training, the ANS's regulating function and coping ability of unemployed population have doubled, and tended toward a dynamic balance.
目前，相当多的研究都致力于开发控制情绪或释放压力的方法。作为心理生理学基础领域的一个应用分支，生物反馈已经发展起来，以满足与这种控制相关的临床和非临床需求。可穿戴医疗设备以一种无处不在的方式，实现了对生命体征的非侵入式监测和新兴生物反馈服务。随着全球经济衰退，失业已成为最严重的社会问题之一；因此，将生物反馈技术与可穿戴技术相结合，用于失业人群的压力管理无疑是有意义的。本文介绍了一种基于集成多生物传感器平台与共振频率训练（RFT）生物反馈策略相结合的可穿戴生物反馈系统，用于失业人群的压力管理。与商业系统相比，多位受试者的现场实验表明，我们的生物反馈系统具有隐蔽性、易于佩戴，并且能够提供可移动的 RFT 生物反馈。此外，借助我们的可穿戴生物反馈系统，在失业人群中进行了为期 3 周的 RFT 生物反馈训练前后自主神经系统（ANS）调节变化的对比研究。结果表明，RFT 生物反馈与可穿戴技术相结合，能够显著增加整体心率变异性（HRV），这表明交感神经活动减少，副交感神经活动增加，ANS 同步性增加。经过 3 周的基于 RFT 的呼吸训练，失业人群的 ANS 调节功能和应对能力提高了一倍，并且趋于动态平衡。
