Guided Acoustic Wave Sensors and Their Applications

Dear Colleagues,

The ongoing trend of digitalization can be seen in a plethora of other trends, such as the Internet of Things (IoT), Industry 4.0, and artificial intelligence (AI). Sensors play a key role in enabling the development of all these innovations, because they are the sources of data. Besides the most prominent optical and MEMS sensors, there are acoustic sensors. This Special Issue is focused on the guided acoustic wave sensors, which are part of the acoustic sensors, since they allow addressing applications that are otherwise hard to solve. Thus, they have their own transformative power with respect to their applications, but also specific challenges that have to be solved to make them robust and reliable. The aim is to show how guided acoustic wave sensors can address applications that other sensors have trouble with, such as harsh environment (high temperatures, high pressures, electronic discharges, corrosive conditions, etc.), how new manufacturing technologies such as three-dimensional (3D)-printing allow for new designs (e.g. the use of metamaterials), and how new algorithms (e.g. the use of AI) lead to better evaluation of measured results.

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. Sensors is an international peer-reviewed open access semimonthly 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 2600 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.
