Special Issue Information

Dear Colleagues,

As we have stated in the introduction of the Section “Actuator Materials”, there are five key trends in the recent development of actuator materials: “Performance to Reliability”, “Hard to Soft”, “Macro to Nano”, “Homo to Hetero” and “Single to Multi-Functional”.

This Special Issue will collect papers on Non-Toxic Actuator Materials. Worldwide toxicity regulation is accelerating the development of Pb-free piezoelectrics as a replacement for conventional PZTs. Piezoelectric polymers and polymer–piezoelectric ceramic composites have been revived and commercialized. “Homo to hetero” structure change is also a recent research trend: stress gradient, in terms of space, in a Pb-free dielectric material exhibits piezoelectric-equivalent sensing capability (i.e., “flexoelectricity”), while electric-field gradient, in terms of space, in a semi-conductive Pb-free piezoelectric material can exhibit bimorph-equivalent flextensional deformation (“monomorph”).

This Special Issue aims to collect advanced research articles and comprehensive reviews in the field of non-toxic actuator materials. Topics of interest include:

  • Advanced Pb-free actuator (piezoelectric/electrostrictive) ceramic materials;
  • Polymer actuator materials (including elastomer actuator materials);
  • Non-toxic composite actuator materials;
  • Non-toxic flexoelectric actuator/sensor materials;
  • Other unique non-toxic actuator materials.

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 1800 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.
