Skin hydration is crucial for overall skin health. Maintaining skin hydration levels preserves skin integrity and prevents tissue damage which can lead to several debilitating conditions. Moreover, continuous monitoring of skin hydration can contribute to the diagnosis or management of serious diseases. For instance, sugar imbalance in diabetes mellitus and kidney disease can lead to the loss of bodily fluids and cause dry skin. Therefore, continuous, accurate and non-intrusive monitoring of skin hydration would present a remarkable opportunity for maintaining overall health and wellbeing. There are various techniques to assess skin hydration. Electrical based Corneometers are currently the gold standard in clinical and non-clinical practice. However, these techniques have a number of limitations. In particular, they are costly, sizeable, intrusive, and operator dependent. Recent research has demonstrated that near infrared spectroscopy could be used as a non-intrusive alternative for the measurement of skin water content. The present paper reports the development and in-vitro validation of a noninvasive, portable, skin hydration sensor. The results indicate that the developed sensor can deliver reliable measurements of skin water content.
皮肤水合作用对整体皮肤健康至关重要。维持皮肤水合水平可保持皮肤完整性，防止组织损伤，而组织损伤可能导致多种使人衰弱的病症。此外，持续监测皮肤水合作用有助于严重疾病的诊断或管理。例如，糖尿病和肾病中的糖失衡会导致体液流失并引起皮肤干燥。因此，持续、准确且非侵入性地监测皮肤水合作用将为维持整体健康和幸福提供一个显著的机会。有多种评估皮肤水合作用的技术。基于电学原理的角质层水合测定仪目前是临床和非临床实践中的金标准。然而，这些技术存在一些局限性。特别是，它们成本高昂、体积庞大、具有侵入性且依赖操作人员。最近的研究表明，近红外光谱可作为测量皮肤含水量的非侵入性替代方法。本文报告了一种无创、便携式皮肤水合传感器的开发及其体外验证。结果表明，所开发的传感器能够提供可靠的皮肤含水量测量值。
