Title: Daiji Uehara: Innovator in Physical Quantity Sensors
Introduction
Daiji Uehara is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of sensor technology, holding a total of 5 patents. His work focuses on the development of innovative physical quantity sensors that enhance measurement accuracy and reliability.
Latest Patents
Uehara's latest patents include a physical quantity sensor and a method for manufacturing the same. This sensor features two substrates and a movable electrode positioned between them. The movable electrode is designed with an elastically deformable diaphragm, which allows for precise detection of capacitance between the diaphragm and a detection electrode on one of the substrates. This design ensures that the coefficients of thermal expansion of the substrates are smaller than that of the movable electrode, optimizing performance across various temperature ranges.
Another notable patent is a converter and method of manufacturing the same, which involves a pressure sensor. This sensor includes an upper substrate with a detection face, a diaphragm that is displaceable, and fixed electrodes on the detection face. The diaphragm is formed by dry-etching single-crystal silicon, which has been treated to lower its specific resistance, enhancing the sensor's functionality.
