Nano-Tactile Scanner with Dust-Proof and Drip-Proof Structure for High-Resolution Measurement of Skin Surface Textures.

Abstract

In this study, we have successfully developed a scanner-type measurement device with a built-in nano-tactile sensor for measuring living organisms and skin surface. A complete sensor protection structure for sensitive tactile sensor device has been developed to achieve a sensing system that is capable of measuring texture changes on the skin surface. By using a highly flexible organic ultra-thin film (film adhesive bandage) as the protective structure, it is possible to prevent deterioration of sensor performance and the intrusion of droplets and dust present on the surface to be measured. This system was used in a clinical experiment at the university's medical faculty, and succeeded in accurately extracting changes in the properties of the patient's skin caused by different wiping methods. As a result, the measurement of tactile texture of the skin surface in various states between dry and wet could be accurately done. Finally, in addition to the ability to measure tactile characteristics of the skin surface, a new function has been realized to measure skin hardness distribution caused by skin changes due to blisters, moles, etc.Clinical Relevance- The developed micron scale was the first to explain the changes in the skin surface structure according to the type of skin surface stimulus and the time of its appearance. It is clinically useful to interpret the protective function of the skin and the function of sensory reception.
