Special Issue Information
Dear Colleagues,
Micromachined Ultrasonic Transducers (MUT) are new types of ultrasonic transducers that have emerged in recent years as a result of the rapid development of microelectromechanical systems (MEMS) technology. Based on the different working principles, MUT is mainly divided into two categories: piezoelectric micromechanical ultrasound transducers (PMUTs) and capacitive micromechanical ultrasound transducers (CMUTs). These two types of micromechanical ultrasonic transducers are based on the piezoelectric and electrostatic effects of acoustic–electric conversion, respectively, and each present beneficial characteristics for different application scenarios. Compared with conventional piezoelectric transducers, MUTs have significant advantages such as a compact structure, low power consumption, and easy integration. These features make them widely used in the fields of medical imaging and therapy, industrial nondestructive testing, and non-contact manipulation, and they have gradually become a research hotspot in next-generation ultrasonic transducers. At the same time, along with the increasing demand for multi-scenario applications, the research and development of low-power, high-performance, and manufacturing-friendly MUT devices has become a key direction to promote the innovative development of ultrasound systems. Therefore, this Special Issue aims to present research papers, short communications, and review articles that focus on the latest technological breakthroughs in the field of MUT, including innovative structural optimization design, development of advanced manufacturing processes, and expansion of cutting-edge application areas.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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.
