Special Issue Information

Dear Colleagues,

Challenges imposed by changes in society and environment require the development of Smart Systems. Active prostheses will, e.g., help the rehabilitation of patients. Drug delivering systems will release drugs, on the basis of well-established protocols. Bio-inspired underwater robots will take care of repetitive or dangerous tasks. Polymeric actuators have been already proposed for the realization of Smart Systems, able to solve even the most complex problems with little or no human intervention, in strategic sectors, such as bio-inspired robotics, aerospace and nanomedicine, just to name a few. Nevertheless, further improvements are needed for realizing polymeric smart autonomous systems and wearable electronics. Smart Systems require embedding sensing and actuating capabilities, signal processing, and electric power generation and management. Flexibility, stretchability, and resiliency are required since Smart Systems will work in unstructured and harsh environments. Moreover, the need for sustainable development requires the realization of environmentally-friendly systems. Miniaturized and biocompatible systems are required for implanted applications.

"More than Moore" solutions will complement silicon-based devices: New materials are needed for guaranteeing a significant diversification, based on novel materials and technologies. Nanotechnologies will be exploited for producing new polymeric materials. Finally, the Industry 4.0 prosumer will be enabled to design and fabricate their own polymeric smart systems. A multidisciplinary approach is required for developing enabling technologies required in such a new scenario.

The realization of the next-generation Smart Systems requires, then, new actuators and stimulus-responsive polymers. It will be necessary to develop new materials, models, production procedures, functional subsystems, design tools, and fabrication systems. Procedures and apparatus for the characterization and validation of such smart systems are also needed.

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 papers will be 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 quarterly 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 1000 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.

Twisted and coiled polymer (TCP) can generate large stroke and output high power density, making it a promising artificial muscle. Thermally induced muscles fabricated from nylon or other polymer fibers can be used in robotic, biomedical devices, and energy-harvesting equipment. While fibers with different shapes and materials have different optimal process parameters. Understanding mechanisms of TCP forming and the impact of process parameters is critical to explore stronger, more powerful artificial muscles. In this paper, an elastic-rod-theory-based model was established for capturing the quantitative relationship between tensile actuation and fabrication load. Further experimental results agree with model calculation and TCP muscles used in our research reaches maximum stroke of 52.6%, strain up to 9.8 MPa, and power density of 211.89 J/kg. Full article
