Special Issue Information

Dear Colleagues,

Application fields of piezoelectric actuators are classified into three categories: positioners, motors, and vibration suppressors. The manufacturing of optical instruments (such as lasers and cameras) must be precise and the positioning accuracy for fabricating semiconductor chips must be adjusted using solid-state actuators (at an order of 0.1 m). With regards to conventional electromagnetic motors, tiny motors smaller than 1 cm are often required in office or factory automation equipment and are rather difficult to produce with sufficient energy efficiency. Ultrasonic motors (whose efficiency is insensitive to size) are superior in the mini-motor area. Vibration suppression in space structures and military vehicles using piezoelectric actuators is also a promising technology.

The so-called “Micromachine Competition” was organized worldwide in the late 1980s by collecting self-propelling machines with the size less than 1cm3; however, this competition was terminated due to the economic recession in the 1990s. This Special Issue, “Piezoelectric Devices and Systems in Micromachines”, will collect articles on the recent developments of piezoelectric and related actuators in terms of new actuator materials, device designs, and drive/control techniques, aiming at self-propelling micromachines with a size of less than 1 cm3. Part of the developments of self-propelling micromachines can be accepted, as long as the content is related to our target.

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.
