Title: Takamitsu Fujiu: Innovator in Vibration Angular-Velocity Sensors

Introduction

Takamitsu Fujiu is a prominent inventor based in Zama, Japan. He has made significant contributions to the field of sensor technology, particularly in the development of vibration angular-velocity sensors. With a total of 8 patents to his name, Fujiu's work has had a substantial impact on various applications in technology and engineering.

Latest Patents

One of Fujiu's latest patents is a process for producing a vibration angular-velocity sensor. In this innovative design, a vibrator is formed on a silicon substrate, which serves as a base through a silicon-processing procedure. A thin film of piezoelectric material is then applied to the substrate using a compatible method. When an alternating current field, close to the resonance frequency of the transverse vibration of the vibrator, is applied to the piezoelectric thin film, it excites characteristic vibrations in the vibrator. If rotational motion occurs along the beam's axis, the Coriolis force is generated, acting perpendicular to both the axial and vibration directions of the beam. This force causes deformation in the beam, allowing for the detection of inductive charges produced in another piezoelectric thin film fixed on the vibrator. This process enables the measurement of rotational angular velocity.

Career Highlights

Fujiu is currently employed at Nikon Corporation, where he continues to innovate and develop advanced sensor technologies. His work at Nikon has positioned him as a key player in the field of precision measurement and sensor design.
