Abstract

This letter presents a glassblown micro-hemispherical shell resonator (

$\mu $

HSR), consisting of a micro-hemispherical shell and a ring-shaped electrode. The blow-molding process is employed to enable the simultaneous fabrication of the electrode and the resonator shell, thereby eliminating assembly errors inherent in traditional discrete assembly methods. Additionally, an innovative S-shaped metal lead is introduced to prevent metal tearing. The experimental results indicate that the surface roughness of the resonator is measured at only 0.217 nm. The resonant frequencies of the drive mode and sense mode are 3.4876 MHz and 3.4891 MHz respectively. Additionally, the Q factor in a 1 Pa vacuum environment is approximately 200 times greater than that at atmospheric pressure. This study offers a novel approach for advancing research on

$\mu $

HSRs.

玻璃吹制微半球壳谐振腔的研制及电致动机构

本文介绍了一种玻璃吹制的微半球壳谐振器（$\mu $ HSR），它由一个微半球壳和一个环形电极组成。采用吹塑工艺实现了电极和谐振腔壳体的同时制造，从而消除了传统离散装配方法所固有的装配误差。此外，一个创新的s形金属引线引入，以防止金属撕裂。实验结果表明，谐振腔的表面粗糙度仅为0.217 nm。驱动模式和检测模式的谐振频率分别为3.4876 MHz和3.4891 MHz。此外，在1pa真空环境中的Q因子大约是大气压下的200倍。本研究为推进$\mu $高铁的研究提供了新的途径。
