Special Issue Information

Dear Colleagues,

The field of actuation systems is very dynamic and profoundly impacts the development of engineering sciences. The development of new materials with piezoelectric, magnetostrictive, and electrostrictive properties, as well as new polymeric materials from the category of elastomers, has generated the possibility of developing new actuators. This Special Issue will cover original experimental and applied research on electroelastic, magnetoelastic, and thermoelastic actuating systems. The scope covers actuators for various disciplines and industries, from advanced manufacturing to automotive, aircraft, aerospace, marine, medical instruments, and robotics. Miniaturization and increasing the precision of electroelastic, magnetoelastic, and thermoelastic actuators are essential requirements in current practical applications. This Special Issue aims to reveal the current efforts and progress in this area. You are welcome to submit a manuscript for this Special Issue. Academic researchers and authors from the industry who are involved in the field are invited to contribute original research articles and reviews (including comprehensive assessments on complete actuator products).

Research areas may include (but are not limited to) the following:

  • Electromagnetic actuator;
  • Magnetostrictive actuator;
  • Piezoelectric actuator;
  • Electrostrictive actuator;
  • Polymer-based actuator;
  • Electrostatic actuator;
  • Thermoelastic actuator;
  • Materials for mechanically driven actuators.

We look forward to receiving your contributions.

A microactuation process was developed with the help of four coils that generate a pulsatory rotating magnetic field. A small actuator stator, which contains a 46 mm acrylonitrile butadiene styrene (ABS) opened box and four coils with E-type ferrite cores, was constructed. Simulations were made for different Duty Cycles, 0.2, 0.5, 0.72 and 0.9, and distances above the E cores, between 0.01 and 6 mm. These simulations determined the magnetic bubble inflating distance, the saturation regions and the average forces that are responsible for nanofluid flow inside the ABS box. An electrical driving scheme was designed, and a drive was constructed to activate four inductive loads that generate a pulsatory rotating magnetic field. The electronic drive can change the actuation frequency (rotation speed) between 1 Hz and 25 Hz and can adjust the Duty Cycle between 5% and 95% (driving force). From simulations and experiments, it was observed that the Duty Cycle must be limited to 0.7 to avoid the magnetic nanofluid saturation at 45 mT. It was found that three applications use a pulsatory rotating magnetic field: a small motor, a small flat pump and a manipulating sheet matrix for displays or chemical droplets mixing. Full article
