Patent: Measurement of skin moisture - capable of simultaneously measuring the surface and deep layers of biological skin.
A unique technology that allows simultaneous measurement of not only the surface of the skin but also its deeper layers.
The moisture content of the skin is measured using electrical conductivity. By innovating the electrode arrangement, we have made it possible to distinguish between the current values in the surface layer and those in the subcutaneous cell layer, allowing for simultaneous measurement of each moisture content. In actual skin, when there is no sweating, the electrical resistivity is high, and it typically shows quite complex conductivity as one moves from the surface to the interior. However, thanks to our unique technology, we have achieved the ability to measure not only the surface of the skin but also the deeper layers simultaneously. The products we handle are based on "accurate measurement technology," represented by systems such as the factory's "quality control inspection system." Therefore, they can also be utilized for research and development, planning, and design of cosmetics, as well as for product testing and quality control. ■ If you would like to customize a skin diagnostic device ■ If you want to develop measurement and analysis equipment for laboratories ■ If you wish to incorporate skin measurement technology into applications or existing measurement devices please feel free to contact us. *For more details, please download the PDF or contact us.

Company information
The parent company of Esquiu, the Japan System Research Institute, was founded in 1968 by Akira Matsushita, the biological father of President Yukio Matsushita and an emeritus professor at Kanagawa University, with the aim of "utilizing research results from universities in the business world." It was a pioneer of "university-originated ventures," which were rare at the time, and in 1982, it succeeded in developing a moisture meter, considered the first skin diagnostic device in Japan. Since then, it has sold over 10,000 skin diagnostic devices (beauty computers) in total. Additionally, the products of the Japan System Research Institute are based on "measurement technology" exemplified by the "quality control inspection systems" used in factories. While having the backing of accurate measurement technology, we propose solutions to realize the "sales activation" of clients selling beauty products and services, tailored to fit their budget.
