Latest Patents

Sanae Tokumitsu holds 2 patents, showcasing her expertise in the design and fabrication of advanced force transducers. One of her latest patents is a "Force transducer and method of fabrication thereof." This invention provides a force transducer with high compression fracture strength and high detection sensitivity, ensuring both precision and reliability. The design features a pressure transfer block that effectively transmits compression forces to narrow strain gauges, which protrude from a silicon substrate. This configuration allows for large compression strains to act on the strain gauges, thereby increasing detection sensitivity. Additionally, when the compression force exceeds a predetermined value, the pressure transfer block contacts the silicon crystal surface, enhancing the fracture strength of the strain gauges. The fabrication of these narrow, protruding strain gauges is achieved through a single mesa etching process.

Another notable patent is the "Semiconductor pressure transducer." This device is designed to detect pressure applied to a diaphragm. It comprises a diaphragm and a pressure detector that includes an Si single crystal, which is oriented to have a crystal face of {110} as the surface for compression force application. The pressure detector features opposing electrodes that are strategically positioned to output a voltage corresponding to the applied compression force.
