Soft Electromagnetic Actuators: Miniature Soft Electromagnetic Actuators for Robotic Applications (Adv. Funct. Mater. 18/2018)

Abstract: Yon Visell and co‐workers describe miniature soft electromagnetic actuators for applications in robotics. The devices, presented in article number https://doi.org/10.1002/adfm.201800244, are based on fine helical inductors fabricated from silicone polymer colloids, eutectic Gallium Indium alloy, and magnetic (NdFeB) powder. Intrinsically deformable actuators are demonstrated for high frequency motion control, including a tactile display and a miniature soft robotic gripper.

“…As shown in Figure 1F and Table S2 (Supporting Information), AI‐LMS exhibits a higher k value and an optimal t value compared to previous investigations involving coils [ 39–47 ] and elastic conductors, [ 48–56 ] thereby ensuring a balanced consideration of both the magnitude and rate of change of the inductive signal. The focus of the Figure 1F is to highlight the advantages of our fabrication approach over other existing methods and to emphasize the potential benefits of using this approach to construct high‐performance AI‐LMS sensors.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…Besides, soft electromagnetic actuator counterparts can generate large forces, for example, a soft helical coil bending actuator can generate 32 mN. [ 51 ] However, the input power reaches 1 W, which is approximately two orders of magnitude higher than the DPE actuator (< 0.018 W). Resistance forces, including mechanical stiffness of DPE and gravitational force, also affect the actuation response.…”

“…Thus, the proposed actuator, which exhibits enhancement of the two main actuator performances based on high E m despite their soft mechanical properties under low operating voltage conditions, is suitable for future flexible and miniaturized robotic applications. [ 11,12 ]…”
