Special Issue Information

Dear Colleagues,

Smart actuator materials, including magnetorheological fluid (MRF), magnetorheological elastomer (MRE), piezoelectric material (PM), shape memory alloy (SMA), shape memory polymer (SMP), dielectric elastomer (DE), etc., have high application potential in soft mechatronics and robotics, such as soft grippers, artificial muscles, wearables, haptics equipment, and biomedical devices. The adaptability, design flexibility, reconfigurability, and versatility of smart soft materials enable applications that are not possible with traditional rigid robots and actuators.

This Special Issue aims to describe various smart actuator materials technologies, provide insight into the latest scientific research in smart materials, and discuss how they are related to actuation and robotic application. We encourage submissions of papers presenting original research findings or novel reviews that could summarize the current state of the art on the topic.

Extended versions of presentations given at the 4D Materials Design and Additive Manufacturing Conference 2023 are also encouraged for this issue. The editors of "Smart Materials in Robotics and Actuators" have extended an invitation to the presenters at 4DMDA 2023 to submit an extended article for peer review and publication in Actuators. You are invited to send your work to this Special Issue dedicated to the 4DMDA2023 conference.

The traditional magnetorheological (MR) damper subject to the limited space has shortcomings such as small damping force, narrow dynamic range and low adaptability. In this study, a new MR damper with folded resistance gaps and bending magnetic circuit was proposed for improving the damping performance. The length of the resistance gap was increased by configuring the multi-stage folded annular gap structure, and the magnetic circuit was established to activate the non-flux region. The mathematical model was established for the MR damper to analyze the damper force, magnetic circuit and dynamic performance. Subsequently, the finite element analysis (FEA) methodology was utilized to investigate the changes of magnetic flux densities in the folded resistance gaps. The test rig was setup to explore and verify the dynamic performance of the proposed MR damper under different excitation conditions. The results indicate the maximum damping force is approximately 4346 N at the current of 1.5 A, frequency of 0.25 Hz and amplitude of 7.5 mm. The damping force and dynamic range of the proposed MR damper are enhanced by 55.82% and 62.21% compared to that of the traditional MR damper at the applied current of 1.5 A, respectively, thus highlighting its high vibration control ability.
