同时测量皮肤的生理和物理特性对于皮肤病的诊断和人体行为的监测非常重要，因为它提供了对皮肤状况的更全面的了解。然而，目前的皮肤分析设备需要每个探头和独特的方案来测量个体皮肤属性，导致测量不便和测量不确定度增加。本文介绍了一种笔式皮肤分析仪，它能同时测量皮肤的三个关键特性：透皮失水率(TEWL)、皮肤电导率和皮肤硬度。它使用单个截断的中空锥(THC)探头，集成了湿度传感器、成对的电极和称重传感器，用于多模式皮肤特性评估。在人体皮肤适宜的范围内，测得TEWL的灵敏度为0.0068(%/S)/(g/m(2)/h)，线性为99.63%；电导的灵敏度为1.02亩S/亩S，线性为99.36%；硬度的灵敏度为0.98Shore 00/Shore 00，线性为99.85%。目前的笔式设备在皮肤健康诊断以及人体行为监测应用方面具有很高的潜力。
Simultaneous measurement of skin physiological and physical properties are important for the diagnosis of skin diseases and monitoring of human performance, since it provides more comprehensive understanding on the skin conditions. Current skin analysis devices, however, require each of probes and unique protocols for the measurement of individual skin properties, resulting in inconvenience and increase of measurement uncertainty. This paper presents a pen-type skin analyzing device capable tomeasure three key skin properties at the same time: transepidermal water loss (TEWL), skin conductance, and skin hardness. It uses a single truncated hollow cone (THC) probe integrated with a humidity sensor, paired electrodes, and a load cell for the multimodal assessment of the skin properties. The present device measured TEWL with a sensitivity of 0.0068 (%/s)/(g/m(2)/h) and a linearity of 99.63%, conductance with a sensitivity of 1.02 mu S/mu S and a linearity of 99.36%, and hardness with a sensitivity of 0.98 Shore 00/Shore 00 and a linearity of 99.85%, within the appropriate ranges for the human skin. The present pen-type device has a high potential for the skin health diagnosis as well as the human performance monitoring applications.
