Extensive Review on Humidity and Moisture on Skin Device Analysis

Abstract

Moisture and humidity influence the skin properties, particularly in the coefficient of friction (CF). In the process of dexterous manipulation, changing in skin hydration will trigger the mechanical properties of object interface and alter the required minimum force to slip any object on the surface. The moisture level of the skin can be obtained based on two principles either the principle of capacitance or conductance. However, there are only few studies reported on the device to measure skin moisture with limited information on the device capacity. On the other hand, currently available devices in the market are mostly manual reported, and it is difficult to find a complete research study on the device prior to marketing. Other devices that are familiar in the aforementioned fields are normally established based on the lab scale standard in comparison with the developed devices, which are not for universal use. For example home-based monitoring or personal skin care routine. Not to mention, the measurement varies from image sensor and many others. Therefore, in this study, the fundamental concept of a device based on pressure sensor was discussed. The information on the quantitative skill measurement was also provided. In the last part, all the devices that are related to moisture and humidity measurement were tabulated and their performances were highlighted.
