Special Issue Information

Dear Colleagues,

With the rapid development of MEMS technology, it could be classified into many fields, such as CMOS MEMS, RF MEMS, optical MEMS, bio-MEMS, and so on. Current nano- and microtechnology provides an effective approach to specifically perform actuation and sensing functions using passive or active manipulations enabling novel breakthrough applications.

This Special Issue on “Basic MEMS Actuators” brings together multidisciplinary interest in one journal entirely devoted to disseminating information on all aspects of research and development of MEMS devices for transducing physical signals. The aim is to publish research on actuators, structures, integrated sensors–actuators, microsystems, and other devices or subdevices ranging in size from millimeters to sub-microns; micromechatronics; microelectromechanical systems; microoptomechanical systems; microchemomechanical systems; microrobots; silicon and non-silicon fabrication techniques; basic studies of physical phenomena of interest to micromechanics; analysis of microsystems; exploration of new topics and materials related to micromechanics; microsystem-related problems such as power supplies and signal transmission; microsystem-related simulation tools; and other topics of interest to micromechanics. This Special Issue on “Basic MEMS Actuators” will publish original papers and invited review articles. The major areas of activity in the development of novel actuators, sensors, and transducers solicited and expected in this Special Issue are within the following device areas:

  • Actuators and microsystems;
  • Packaging and solid-state materials and fabrication processes;
  • Nanoscale materials and fabrication;
  • Composite materials, polymers, and fabrication processes;
  • Microfluidic platform technologies;
  • Energy, power, and thermal management;
  • Chemical sensors and microsystems;
  • Biosensors and microsystems including in vitro medical applications;
  • Wearable and in vivo medical devices and microsystems;
  • Physical sensors and microsystems;
  • Rf mems, resonators, and oscillators;
  • Optical and atomic transducers.

Experimental results, as well as design, simulation, and theory on each topic are of interest.

The piezoelectric thin film composed of single-crystal lithium niobate (LiNbO3) exhibits a remarkably high electromechanical coupling coefficient and minimal intrinsic losses, making it an optimal material for fabricating bulk acoustic wave resonators. However, contemporary first-order antisymmetric (A1) Lamb mode resonators based on LiNbO3 thin films face specific challenges, such as inadequate mechanical stability, limited power capacity, and the presence of multiple spurious modes, which restrict their applicability in a broader context. In this paper, we present an innovative design for A1 Lamb mode resonators that incorporates a support-pillar structure. Integration of support pillars enables the dissipation of spurious wave energy to the substrate, effectively mitigating unwanted spurious modes. Additionally, this novel approach involves anchoring the piezoelectric thin film to a supportive framework, consequently enhancing mechanical stability while simultaneously improving the heat dissipation capabilities of the core.
