Special Issue Information
Dear Colleagues,
Piezoelectric actuators are often used in precision positioning devices because of their nanometer-order resolution. In addition, they are small and light and generate a large blocking force. On the other hand, the deformation of piezoelectric actuators is generally limited to several tens of micrometers. In order to overcome this disadvantage, they are often combined with mechanisms to enlarge their movable range by accumulating minute motions. Since hysteresis and creep also deteriorate the performance of the piezoelectric actuators, the displacement, supplied electric charge or driving current is fed back for closed-loop or sensorless control methods. Some models that compensate for the hysteresis also have been studied. Smart structures with collocated piezoelectric composite can suppress vibration. These developments expand and enhance their applications to science, technology, precision engineering, and industry such as material science, space science, nanotechnology, biotechnology, precision machining, and semiconductor production. This Special Issue will collect contributions related (but not limited) to the following topics: Design of piezoelectric positioners, movers, and motors; driver for piezoelectric actuators; control strategy of piezoelectric actuators; modeling/simulation of piezoelectric actuators; piezoelectric energy harvesting; piezoelectric transducers; piezoelectric composites and smart structures; piezoelectric and structural health monitoring; near-field ultrasonic levitation; and applications to science, technology, precision engineering, and industry.

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. Actuators 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 2400 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.
