压力会导致头痛和疲劳，加速成瘾行为（例如，吸烟、酗酒和吸毒），并导致心血管疾病和癌症。来自传感器的压力的连续评估可用于及时递送各种干预以减少或避免压力。我们调查的可行性，通过两个领域的研究，使用无线生理传感器的连续压力测量-一个为期四周的研究与非法药物使用者（n = 40），和一个为期一周的研究与日常吸烟者和社会饮酒者（n = 30）。我们发现，在为期4周的研究中，可以获得11+小时/天的可用数据。第一周后观察到显着的学习效果，即使在第四周，数据产量也会随着时间的推移而增加。我们提出了一个框架来分析传感器的数据产量，并发现在无线信道中的损失是可以忽略不计的，在进一步提高数据产量的主要障碍是附着约束。我们展示了在感兴趣的事件之前测量压力分钟的可行性，并观察到传感器产生的压力在自我报告的压力和吸烟事件之前上升。
Stress can lead to headaches and fatigue, precipitate addictive behaviors (e.g., smoking, alcohol and drug use), and lead to cardiovascular diseases and cancer. Continuous assessment of stress from sensors can be used for timely delivery of a variety of interventions to reduce or avoid stress. We investigate the feasibility of continuous stress measurement via two field studies using wireless physiological sensors — a four-week study with illicit drug users (n = 40), and a one-week study with daily smokers and social drinkers (n = 30). We find that 11+ hours/day of usable data can be obtained in a 4-week study. Significant learning effect is observed after the first week and data yield is seen to be increasing over time even in the fourth week. We propose a framework to analyze sensor data yield and find that losses in wireless channel is negligible; the main hurdle in further improving data yield is the attachment constraint. We show the feasibility of measuring stress minutes preceding events of interest and observe the sensor-derived stress to be rising prior to self-reported stress and smoking events.
