Advanced Application in Smart-Fluid-Based Sensors and Actuators

Dear Colleagues,

Smart fluid is a liquid-based system with collective properties endowed by the cooperation of the dispersoid and dispersant phases, whose single agents or constituents enable the emergence of smart distributed functionalities such as information processing capabilities, self-powering, sensing capabilities, and mobility. Commonly recognized smart fluids include, but are not limited to, ferrofluid, liquid metal, magneto(electro)rheological fluid, ionic liquid, nanoparticle/liquid-crystal colloids, and photorheological fluid. The sensing and actuating capabilities of smart fluid mainly come from two mechanisms. The first is the internal transformation of their microscopic state, such as phase transition, cross-linking, or formation of anisotropic microstructures. The second is the mobility of the smart fluid under external stimulus, which can be regarded as the ideal sensing form to detect the deformation of soft electronics or robots. Additionally, different kinds of smart fluid can be adopted simultaneously in the formulation of advanced flexible systems, which may provide new paradigms for future applications, such as smart-fluid-based soft robotics, stiffness controllable/sensible wearable devices, and even in vivo smart structures. This Special Issue encourages authors to submit experimental or theoretical research on the keywords below, and works on relevant fields are also considered.

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. Sensors is an international peer-reviewed open access semimonthly 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.
