Special Issue Information
Dear Colleagues,
The measurement of minute changes in mass or properties of gases and liquids is best approached by making use of electromechanical resonances. The classical example is the piezoelectric quartz microbalance to weigh thin films. Applications in liquids range from condition monitoring for engine oils to highly specific biosensors. With the rise of MEMS technology, the principle of resonant sensors was realized in a wide variety of devices, such as microcantilevers or miniaturized tuning fork resonators. In addition to piezoelectricity, actuation and readout is realized using capacitive, electrodynamic, electro- and magnetostrictive, thermal, and optical transduction mechanisms. The interaction with a surrounding fluid often requires concise analysis of pressure and shear-wave acoustics. Nonlinear effects are regularly observed at higher vibration amplitudes due to deviations from Hooke’s law for spring structures or fluid streaming effects. While the field of applications continuously expands, modeling using analytical and numerical models becomes increasingly important.
The Special Issue on Resonant Microsensors addresses recent advances in the field focusing on fabrication, analysis, and application. A topical workshop will be organized in May 2020 at JKU Linz, Austria. You are welcome to preregister by email to [email protected] to stay informed about the upcoming activities. Participants are invited to submit a contribution to the MDPI Micromachines Special Issue on Resonant Microsensors by September 1st, 2020.

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 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.
