Looking back at thirty years of microsystem development, micro actuators have proved themselves to be the key elements for almost all kinds of microsystems. Hardly found as stand-alone components, they are typically integrated into systems. The most obvious example, and simultaneously the most popular device, is the electrostatic comb actuator, which is found as an integrated part of innumerous inertial sensors. Its unique success is due to its simple and scalable design, and its reliable integrated manufacturing process via the ICP. In addition, magnetic, piezoelectric, shape memory, pneumatic, and hydraulic principles have been explored for micro actuation, each of which have its own limits of integration, process complexity, and applicability. Also, over the past few years, living cells, such as cardio myocytes, muscle cells, and whole dorsal vessels, have been combined with technical systems and have resulted in new types of bio micro actuators. However, most of them problematically require an aqueous environment and only have a limited lifetime.
There potential applications of micro actuators are wide-ranging and include inertial sensors, optical MEMS and lab-on-a-chip, manipulators, micro robots, and micro surgery. Each domain has its typical requirements in terms of forces, displacements, materials, frequencies, voltage vs. current control, etc.
For this Special Issue, we encourage reviews on actuation mechanism classes and classes of application. We also encourage the submission of regular papers on new actuators.

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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Micromachines is an international peer-reviewed Open Access monthly journal published by MDPI.
