Special Issue Information
Dear Colleagues,
Richard Feynman, in his famous talk at the APS in Caltech in 1959, discussed the possibilities of building small machines that could be swallowed and used as a mechanical surgeon to remove a faulty heart valve or assist an inadequately performing organ. It is not hard to imagine that the backbone of such mechanical surgeons would one day consist of micro- and nano-actuator technologies that can convert heat/light/charge/chemicals within the body into mechanical work. Feynman’s wild ideas eventually gave way to several innovative technologies namely scanning probe microscopies, micro-electro-mechanical systems and nanotechnology. Nanomaterials such as 1D carbon nanotubes and 2D graphene are excellent actuators owing to their high strength and elastic modulus due to the strong sp2 carbon bonds that make up their structure. Since the pioneering work by R.H. Baughman on carbon nanotube actuators in 1999 in Science, this field has seen a tremendous growth with more than thousand publications on various types of nanotube/graphene-based actuators. Some interesting innovations in these areas include the case of the smallest man made nanomotor based on a single nanotube rotating a metallic paddle by Zettl in 2003. Arrays of small nanomotors with molecular mechanisms could eventually be the building blocks of a mechanical factory that could be useful in detecting atoms and molecules, deflecting/filtering electromagnetic radiation, and splicing proteins/damaged cells with a rotating knife patterned onto the paddle inside an artery/vein, not far from the wild dream that Feynman imagined. Recent advances in 2-D nanomaterials such as molybdenum sulphide has shown the coupling between piezoelectric behaviour and semiconducting properties (Piezotronics) depending on the number of layers and is sure to impact the field of energy conversion and actuation in intriguing ways. Therefore this Special Issue targets high quality publications spanning the following topics:
- 1D and 2D actuators based on carbon nanotubes, graphene and other 2-D materials and their composites including soft actuators.
- Mechanisms, such as electro-mechanical, pneumatic, piezoelectric, photo-mechanical, photo-thermal, shape memory, and others incorporating nanomaterials and their composites.
- Actuator devices, processing technologies and underlying principles governing the working of such devices at all length scales
- Theoretical modeling.
- Scalable manufacturing of 1D and 2D nanomaterials for actuation and energy conversion technologies
- Actuation, Robotics and other energy conversion applications

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.
