Title: Kazutaka Uda: Innovator in Moisture-Sensitive Devices
Introduction
Kazutaka Uda is a notable inventor based in Tenri, Japan. He has made significant contributions to the field of moisture-sensitive devices, holding a total of 5 patents. His work focuses on creating innovative solutions that accurately measure humidity and other atmospheric conditions.
Latest Patents
One of Uda's latest patents is a moisture-sensitive device that includes a substrate, such as a silicon substrate, and a pair of belt-like heating elements. These elements extend over recesses formed in the substrate and are composed of a resistive film made of platinum or nickel. A heat-resistant insulating film covers the resistive film, allowing one heating element to act as a detector and the other as a reference. This device can precisely determine absolute humidity, even with sudden temperature changes.
Another significant patent is a sensor that features a pair of sensor units. One unit serves as a detecting sensor, while the other acts as a reference sensor. Each unit comprises a substrate with a hollow portion and a thin insulating layer shaped like a bridge, cantilever, or diaphragm. The sensitive film is placed on this layer, and a pair of electrodes contacts the sensitive film. The detecting sensor unit's sensitive film is exposed to the atmosphere being measured, allowing its electrical resistance to change with variations in physical quantities. In contrast, the reference sensor unit's sensitive film is sealed within a shielding container, ensuring that its electrical resistance remains unaffected by external atmospheric changes.
Career Highlights
Kazutaka Uda has worked with prominent companies, including Sharp Corporation and 501 Sharp Corporation. His experience in these organizations has contributed to his expertise in developing advanced sensor technologies.
