用可穿戴设备监测指尖血流和组织活性，评估压力相关症状。
A Wearable Device Dataset for Mental Health Assessment Using Laser Doppler Flowmetry and Fluorescence Spectroscopy Sensors
- 通过激光多普勒血流仪与荧光光谱传感器采集生理信号。
- 132名跨19国成人数据表明血流与组织活性模式关联压力症状。
- 适合关注无创心理健康监测的临床与健康科技研究者。
全球数以百万计的人受压力、焦虑和抑郁等心理健康问题影响。当前评估多依赖自我报告问卷，易受主观偏差影响。本研究探索可穿戴设备通过身体物理信号评估心理健康的可行性。设备从指尖采集微小的血流变化与组织活动数据。我们收集了来自132名成人的数据，覆盖19个国家，并将这些生理信号与心理健康问卷结果进行对比。研究发现，血流和组织活性的特定模式与压力相关症状存在显著关联。该方法有望推动日常生活中简便、非侵入式心理健康监测工具的发展。代码与数据集已公开：https://github.com/leduckhai/Wearable_LDF-FS。
原文摘要 · Abstract (English)
Mental health problems such as stress, anxiety, and depression affect millions of people worldwide. These conditions are usually assessed using questionnaires, which rely on how people describe their own feelings. In this study, we explore whether a wearable device can help measure mental health using physical signals from the body. The device records small changes in blood flow and tissue activity from the fingertip. We collected data from 132 adults across 19 countries and compared these signals with mental health questionnaire results. We found that patterns in blood flow and tissue activity are linked to stress-related symptoms. This approach may help develop new tools for simple, non-invasive mental health monitoring in everyday life. Code and datasets are publicly available: https://github.com/leduckhai/Wearable_LDF-FS
