Design, application, marketing, and social impact of non-contact impedance sensor

This paper discusses the design, application, marketing and social impact of non-contact impedance sensor that can measure the impedance of environment. The developed sensor is composed of a displacement sensor and air (or water) force supply nozzle. The applications of the developed sensor are human skin age, medical fields, foods, and industrial products. We show the design based on our patent (#2002-329145) and prospect the expected market. We also show the social impact for releasing the sensor in the market.
