Title: Naomasa Sunano: Innovator in Gas Sensor Technology
Introduction
Naomasa Sunano is a notable inventor based in Akashi, Japan. He has made significant contributions to the field of gas sensor technology, holding a total of 3 patents. His innovative work focuses on enhancing the performance and reliability of gas sensors.
Latest Patents
Sunano's latest patents include a gas sensor and a method of producing the same. The first patent describes a gas sensor that features a pair of electrodes printed on an electrically insulating substrate. A sensitive layer is deposited on the tip portions of the electrodes and a part of the substrate adjacent to the tip portions, bridging the space between the electrodes. A protective film is also deposited on the electrodes, ensuring that a part of each electrode covered with the sensitive layer remains free of the protective film. The sensitive layer is formed by depositing titanium oxide through plasma spraying on the substrate, followed by heat treatment to create a diffusion reactive layer and fine grooves on the surface of the sensitive layer.
The second patent outlines a gas sensor constructed with an electrically insulating base, electrodes formed on the base, and a gas-sensitive film on the surface where it detects gases, such as oxygen. This gas sensor is characterized by a thermal-sprayed film made of an oxide with a perovskite structure. The film's surface is designed with fine cracks to increase its effective surface area, thereby speeding up the response time. The thermal spraying process is carefully controlled to prevent impurities from affecting reliability. Additionally, the gas-sensitive film may be coated with a ceramic material to enhance performance and protection.
