Special Issue Information
Dear Colleagues,
Acoustics is one of the key forms of mechanical energy that is exerted everywhere in our world. It helps with sensing, actuating, and communicating, and even helps in medical or industrial matters. With a broad operating spectrum, it serves as the most pivotal tool in various implementations, ranging from airborne applications to studies through different media, especially for needs beyond the physical limitations of other mechanisms (e.g., optical or electromagnetic waves). Alongside the progression of advanced transducer technology, more acoustic device alternatives have been optimized for conventional applications. In addition, consistent research efforts in the field of frontier transducers enable rapid paradigm shifts in many emerging acoustic applications, which coherently accelerate the development of other peripheral technologies, such as thin-film materials used in acoustic transducers, circuits for acoustic devices, modules, algorithms, system integration, and even the integration of acoustic sensors into smart systems. In order to promote research efforts and advocate for continuous innovation in this field, in this Special Issue the current state of the art in the field of ‘acoustic transducers and their applications’ will be presented, covering a wide range of related topics, including, but not limited to, the following:
- New piezoelectric materials: ceramics, thin films, single crystals, polymers, composites, 2D materials, etc.;
- Acoustic transducers: acoustic sensors and actuators, circuits for acoustic devices, modules, algorithms, and integrated systems;
- Piezoelectric devices/acoustic transducers: fabrication, testing, characterization, design, modeling, simulation, manufacturing, 3D printing, packaging, and system integration;
- Acoustic transducer applications: nondestructive testing, acoustic arrays for holograms and beam steering, acoustic ranging, acoustic lenses, meta-materials and meta-surfaces, energy harvesting, medical imaging, wearable sensors, biomedical applications, virtual reality/augmented reality, and other emerging applications for the metaverse.

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.
