Quartz Resonators and Their Application in Frequency Devices and Sensors

Dear Colleagues,

The applications of quartz resonators fall into two main categories. First, owing to their exceptional frequency stability, they serve as critical components in signal processing, frequency control, and time base. They are the core components of frequency devices, such as oscillators and filters, which are widely used in electronic communication systems. Second, the variation in their resonance frequency is linearly related to physical parameters such as temperature, acceleration, force, and pressure, enabling their use as sensors for these quantities.

Research on quartz resonators correspondingly follows two parallel directions. One focuses on improving frequency stability, ensuring reliable performance under varying environmental conditions while progressively achieving higher operating frequencies. This demands an in-depth investigation into multiphysics modeling of electromechanical-thermal coupling nonlinearities, structural optimization, material innovation, fabrication techniques, novel circuit design, and advanced packaging solutions. The second direction focuses on enhancing sensor performance—specifically resolution, sensitivity, measurement range, and long-term durability.

The goal of this Special Issue is to seek high-quality research and review articles that advance the fundamental understanding and practical applications of quartz resonators, with a specific focus on enhancing their performance in frequency control devices and physical sensors.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Micromachines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
