Miniaturized and Micro Actuators
A section of Actuators (ISSN 2076-0825).
Downsizing an actuator is the basic task for operating miniaturized, micro, and nanosystems. The design of such a servomechanism implies the transformation of a certain amount of energy and, then, power control and transmission. Unfortunately, the design criteria adopted at the macro scale cannot always be applied because of the scaling phenomena and so a new paradigm for actuator design must be set up. Actuation takes into account parameters that are often contrasting with each other, such as precision in motion, low and independent power, large displacement, actuation force, and integration with the other subsystem. Therefore, different methods and physical principles have been employed and different actuation types have been employed, such as electrostatic, piezoelectric, thermal, fluid, and even electromagnetic, but a long and arduous road remains ahead.
The Miniaturized and Micro Actuators Section has been launched for original contributions (Articles, Reviews, Communications, Book review, Brief and Case reports, Comment papers, Technical notes, and Letters) that will help to improve the actual scenario, namely, to better understand the microsystem actuation tasks and principles, with relation to the involved physical phenomena, to simulate microsystem actuation in a multi-physic context, to improve experimental testing methods and specific technological processes for the fabrication of miniaturized actuator systems, to present original electromechanical designs for miniaturized systems, MEMS and NEMS, and, finally, to present innovative and original applications in the largest possible variety of fields, such as the following, only representative, examples: biology, medicine, surgery, ocean engineering, energy, manufacturing, automotive, and aerospace.
