Electrodermal activity (EDA) is an electrical property of the human skin, correlated with person's psychological arousal. Nowadays, different types of EDA measuring devices are used in highly versatile fields-from research, health-care and education to entertainment industry. But despite their universal use the quality of their measuring function (their accuracy) is questioned or investigated very seldom. In this paper, we propose a concept of an EDA patient simulator-a device enabling metrological testing of EDA devices by means of a variable resistance. EDA simulator was designed based on a programmable light-controlled resistor with a wide resistance range, capable of simulating skin conductance levels (SCL) and responses (SCR) and was equipped with an artificial hand. The hand included electrically conductive fingers for attachment of EDA device electrodes. A minimal set of tests for evaluating an EDA device was identified, the simulator's functionality discussed and some testing results presented.
皮肤电活动（EDA）是人体皮肤的一种电特性，与人的心理唤醒有关。如今，不同类型的 EDA 测量设备被广泛应用于从研究、医疗保健和教育到娱乐行业等各个领域。但是，尽管它们被广泛使用，但其测量功能（准确性）的质量却很少受到质疑或调查。本文提出了一种 EDA 患者模拟器的概念，该模拟器通过可变电阻来实现对 EDA 设备的计量测试。EDA 模拟器是基于可编程光控电阻器设计的，具有宽电阻范围，能够模拟皮肤电导水平（SCL）和反应（SCR），并配备了一只人工手。该手包括用于连接 EDA 设备电极的导电手指。确定了一组用于评估 EDA 设备的最小测试集，讨论了模拟器的功能，并展示了一些测试结果。
