Measurement of Skin Hydration Using IoT Devices = Measurement of Skin Hydration Using IoT Devices

다국어 초록 (Multilingual Abstract)

Non-invasive measurement of skin functions, such as epidermal permeability barrier function, skin hydration and skin surface pH, generally requires specialized apparatus and controlled environmental conditions (i.e., temperature and relative humidity). While these data can provide invaluable information about the skin functions, they can only represent skin functions under specific experimental conditions. In order to analyze the changes of skin functions according to the practical environmental changes, such as by seasonal change or air pollution status, large number of data sets over a long-term measurement period are required. Considering the price and measurement protocols, classical measurement apparatuses are not practically applicable for these kinds of studies. Recent advances in IoT (internet of things) technology and sensor technology have made it possible for developing various kinds of wearable devices, which can track and record enormous number of data sets from human behaviors. Recently, we developed a portable device that measures the skin hydration and stores the data using IoT technology. Hypothetically, it can provide enough data sets which make it available to analyze the overall tendency of skin functions. While there are clear limits of these approaches, such as uncontrolled measurement conditions and non-standardized measurement protocols, big data analysis may overcome these limitations. In this talk, results of preliminary study will be discussed and further study plans with the device will suggested.
