With a total of 5 patents to his name, Sango's work has had a considerable impact on various applications.
Latest Patents
One of Sango's latest patents is a vibration angular-velocity sensor and the process for producing it. This invention involves forming a vibrator 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 vibrator's transverse vibration, is applied, the piezoelectric reverse effect excites characteristic vibrations in the vibrator. If rotational motion occurs along the beam's axis, the Coriolis force is generated, leading to deformation of the beam. By detecting the inductive charges produced in another piezoelectric thin film fixed on the vibrator due to this deformation, the rotational angular velocity can be accurately measured.
Another significant patent by Sango is a piezoelectric vibration angular velocity meter and a camera utilizing the same technology. Upon activation, the device employs a forced excitation driving circuit to supply an oscillation output pulse to the vibrator, ensuring it vibrates at its resonance frequency. Once the vibrator reaches a stationary state, the system transitions to a self-excitation mode, allowing for continuous operation.
