Title: Innovations of Katsuhiko Ariga
Introduction
Katsuhiko Ariga is a notable inventor based in Obu, Japan. He has made significant contributions to the field of pressure-sensitive technology and membrane switches. With a total of 3 patents, his work showcases innovative solutions to common challenges in electronic components.
Latest Patents
One of his latest patents is a pressure-sensitive transducer that features a pressure-sensitive layer. This layer includes high conductivity flaky carbon particles and low conductivity amorphous-based carbon particles. These particles are bound together by a resin-system binder. When a pushing force is applied to the resin films, the average distance between the carbon particles decreases, leading to a tunnel conduction phenomenon. This results in a decrease in conductive resistance between the electrodes, enhancing the pressure sensing property.
Another significant patent is a membrane switch designed with a migration suppression feature. This switch aims to suppress the growth of metallic ion crystals caused by condensation. It consists of first and second metallic conductive layers placed inside the first and second resin films, respectively. Non-metallic conductive layers cover these metallic layers, while a spacer separates them and defines a spacer cavity. The design ensures that at least one of the metallic conductive layers is positioned a prescribed distance from the spacer inner wall, providing a pathway for metallic ion crystal migration.
