皮肤电活动(EDA)是一项重要的情感指标，通常使用桌面传感仪器在手指上进行测量。最近，新一代可穿戴、电池供电的EDA设备应运而生，鼓励EDA传感转移到身体的其他位置。为了研究这种传感器/位置变化在心理生理学研究中的意义，我们进行了一个验证性实验。在这项实验中，我们使用惊吓刺激来瞬间唤醒n=23名受试者坐着时的交感系统。惊吓刺激是标准但最小的应激源，因此是确定传感器和位置分辨率极限的理想选择。实验表明，无论是使用传统的还是移动的EDA传感器，精确测量手指和手掌上的微小EDA响应都是可行的。相比之下，精确测量鞋底上的微小EDA反应是具有挑战性的，而在手腕上甚至检测到这种反应对于两种EDA模式都是有问题的。鉴于情感腕带已经成为EDA传感的主要形式，研究人员应该警惕这些限制。
Electrodermal activity (EDA) is an important affective indicator, measured conventionally on the fingers with desktop sensing instruments. Recently, a new generation of wearable, battery-powered EDA devices came into being, encouraging the migration of EDA sensing to other body locations. To investigate the implications of such sensor/location shifts in psychophysiological studies we performed a validation experiment. In this experiment we used startle stimuli to instantaneously arouse the sympathetic system of n=23 subjects while sitting. Startle stimuli are standard but minimal stressors, and thus ideal for determining the sensor and location resolution limit. The experiment revealed that precise measurement of small EDA responses on the fingers and palm is feasible either with conventional or mobile EDA sensors. By contrast, precise measurement of small EDA responses on the sole is challenging, while on the wrist even detection of such responses is problematic for both EDA modalities. Given that affective wristbands have emerged as the dominant form of EDA sensing, researchers should beware of these limitations.
