Special Issue Information

Dear Colleagues,

In recent years, emerging actuators such as shape memory alloy (SMA)-based actuators have made it possible to overcome the current limitations of conventional actuators by being integrated into various applications, including medical robotics, rehabilitation robotics, automotive and aerospace industry applications, and more.

Due to their promising properties, SMA-based actuators have received much attention from researchers, where topics related to materials, actuator design, and control are addressed to improve their performance depending on the final application.

This Special Issue addresses research on SMA-based actuators from fundamental studies to their final applications. Original research and review articles are recommended. Topics include, but are not limited to, the following:

  • Control of SMA actuators;
  • Emerging design and fabrication of SMA actuators;
  • Performance assessment of SMA (e.g., electrical power consumption, efficiency);
  • Sensorless actuator;
  • SMA actuators for robotic applications.

Shape memory alloys (SMAs) exhibit a unique property that undergoes deformation in response to temperature variation. This characteristic can be utilized via the application of a filiform SMA wire to tendon-driven robotic actuators for biomimetic joint movements. However, due to the inefficiencies in heat dissipation, conventional SMA tendon-driven actuators are characterized by their lower relaxation speeds than other actuators. This paper proposes a novel cooling design for an SMA tendon-driven actuator using thin-fin heat sinks based on a multi-layer wrapped SMA tendon design. In addition, the electric circuit and the controller are refined. Prototype devices are constructed to validate the performance of SMA-based actuators under PID control. The results indicate that the proposed design exceeds previous models in terms of relaxation performance by up to 5.8 times while also being able to stabilize at a target angle within 0.5 s under control.
