RESONATOR AND RESONANCE DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18669835 titled 'RESONATOR AND RESONANCE DEVICE

Simplified Explanation: The patent application describes a resonator with a unique structure that includes a vibrating portion, a holding portion, and a support portion. The vibrating portion has a recessed or protruding shape on one side of the substrate.

  • The resonator includes a vibrating portion with a substrate and a piezoelectric layer.
  • It also has a holding portion surrounding part of the vibrating portion in a plan view.
  • A support portion is present between the holding portion and the vibrating portion to provide support.
  • The vibrating portion consists of a first and second portion, with the second portion being thicker than the first portion.
  • The shape of the vibrating portion on the side opposite to the piezoelectric layer is either recessed or protruding.

Potential Applications: 1. Frequency control devices 2. Sensors 3. Oscillators

Problems Solved: 1. Enhanced vibration control 2. Improved resonator performance

Benefits: 1. Higher precision in frequency control 2. Increased sensitivity in sensors 3. Enhanced stability in oscillators

Commercial Applications: The technology can be utilized in industries such as telecommunications, automotive, and consumer electronics for applications requiring precise frequency control and vibration sensing capabilities.

Questions about Resonator Technology: 1. How does the unique structure of this resonator improve its performance compared to traditional designs? 2. What are the potential challenges in manufacturing resonators with such intricate designs?

Frequently Updated Research: Researchers are continually exploring ways to optimize the design and materials used in resonators to further enhance their performance and applications.


Original Abstract Submitted

A resonator that includes: a vibrating portion including a substrate, and a piezoelectric layer on the substrate; a holding portion around at least a part of the vibrating portion in a plan view of the substrate; and a support portion between the holding portion and the vibrating portion and that supports the vibrating portion. The vibrating portion includes a first portion and a second portion, a thickness of the second portion in a thickness direction of the substrate is larger than a thickness of the first portion in the thickness direction, and the vibrating portion has a recessed shape or a protruding shape defined by the first portion and the second portion on a side of the substrate opposite to the piezoelectric layer.
