Elimination of Necking and Aspect Ratio Dependence in Uniaxial Actuators by Continuous Fiber Reinforcement

open access: yesAdvanced Robotics Research, EarlyView.
A novel carbon fiber reinforcement for dielectric elastomer actuators enhances actuation force while decoupling electromechanical performance from the actuator's aspect ratio. Unlike conventional fiber reinforcements, it enables a uniform planar stretch state along the entire actuator.

Enabling Real‐Time Shape‐Sensing in Soft Robots via a Miniaturized, Single‐Signal, Color‐Tuned Soft Optical Sensor

open access: yesAdvanced Robotics Research, EarlyView.
A miniaturized soft optical sensor that uses thin film color tuning enables real‐time 3D shape‐sensing from a single red–green–blue (RGB) signal. When integrated into a soft robot, it enables closed‐loop control and autonomous navigation in a phantom lung environment without the need for onboard electronics, achieving sub‐millimeter accuracy through ...

Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots

open access: yesAdvanced Robotics Research, EarlyView.
A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.

High Performance Nonaqueous Ca‐Ion Cathodes Based on NASICON‐NaV2(PO4)3 and the Way to Activate Their Structure

open access: yesAdvanced Sustainable Systems, EarlyView.
This study highlights the activation mechanism for calcium storage in NASICON‐NaV2(PO4)3, showcasing it as an effective cathode for calcium‐ion batteries at room temperature. It delivers a discharge capacity of 106.9 mAh g−1 (82% improvement) at ≈3.5 V (vs Ca/Ca2+), with good cyclability, offering insights for developing high‐performance cathodes for ...

Regular versus Irregular Exercise Differentially Modulates Hippocampal‐Hepatic Acetylcholine Flux to Coordinate Fear Memory Extinction and Liver Inflammation

open access: yesAdvanced Science, EarlyView.
Ma et al. report the hippocampal and hepatic acetylcholine (ACh) levels are differently modulated by regular versus irregular exercise, which contributes to coordinate hippocampal astrocyte activity and hepatic FBXL6high neutrophil recruitment. This ACh‐modulated brain‐liver circuit links the effects of exercise on fear memory extinction and liver ...
