Highly Dynamic Soft Electrohydraulic Origami Actuators for Agile and Multimodal Robotic Locomotion

SmartBot, Volume 2, Issue 2, June 2026.
Most current soft robots still lag far behind their natural counterparts in both agility and speed, mainly attributed to the limited morphing modes and performance of soft actuators. Here, the authors report a new methodology of electrohydraulic origami (EHO) for creating powerful and multimodal soft actuators with large strain, high speed, lightweight,

Modeling and Characterization of a Self‐Sensing Soft Hydraulic Muscle

Advanced Intelligent Systems, Volume 8, Issue 5, May 2026.
This article presents the self‐sensing soft hydraulic muscle (SSHM), a novel soft actuator capable of simultaneously sensing force and length without external sensors. A comprehensive model accurately predicts SSHM behavior, validated experimentally with minimal errors. Using propylene glycol enhances durability and reduces hysteresis.

Scalable High‐Force Zipping Electrostatic Actuators

Advanced Intelligent Systems, Volume 8, Issue 5, May 2026.
An electrostatic actuator architecture is presented that combines high energy density with forces and strokes suited for wearable soft robotics. By folding patterned thin films into a scalable honeycomb of zipping units, performance becomes tunable through series–parallel design, achieving over 40 N and 28 J/kg.
