The importance of continuous monitoring of skin hydration in daily life, to aid in the diagnosis of skin diseases, is rising. Electrodes that can be worn directly on the skin are attracting attention as an effective means. However, they should not inhibit natural water evaporation from the skin and should not cause inflammation or irritation even if they are attached to the body for long periods of time. In this study, nanomesh electrodes that have previously been reported to exhibit high biocompatibility are also found to exhibit high water vapor permeability, resulting in properties that prevent skin dampness. Furthermore, the skin impedance measured using nanomesh electrodes is found to correlate with the hydration level of skin measured using existing medical equipment. This study provides a new approach to measure skin hydration in conditions close to bare skin.

使用纳米网状电极进行皮肤阻抗测量，以监测皮肤水合作用

在日常生活中不断监测皮肤水合作用以帮助诊断皮肤疾病的重要性正在上升。可以直接戴在皮肤上的电极作为一种有效的方法引起了人们的注意。但是，即使它们长时间附着在身体上，它们也不应抑制皮肤中自然水的蒸发，也不应引起炎症或刺激。在这项研究中，先前已报道具有高生物相容性的纳米网电极也被发现具有高水蒸气渗透性，从而具有防止皮肤潮湿的特性。此外，发现使用纳米网状电极测量的皮肤阻抗与使用现有医疗设备测量的皮肤的水合作用水平相关。
