Liquid Crystal Elastomer Actuator Matrix for Large Area Applications

Advanced Materials Technologies, EarlyView.
A scalable approach is used to manufacture a digitally‐controllable, 2D 5 × 5 actuator matrix. The elements of the matrix are produced by direct ink writing of a liquid crystal elastomer ‘artificial muscle’ on large‐area flexible thin‐film heaters. In optimizing the low‐power actuators, multiple heater designs and substrate materials are investigated ...

Spatial Stiffness Programming in Single‐Filament Material Extrusion Through Data‐Driven Thermal Foaming

Advanced Materials Technologies, EarlyView.
Single‐filament material extrusion enables spatial stiffness programming through locally controlled thermal foaming of TPU. A data‐driven G‐code framework tunes porosity from 15.7% to 40.7% and hardness from 90 to 63 Shore A within and across layers. Monolithic hands and soft actuators consequently achieve distinct programmed motions without material ...

3D‐Printed Actuator Powered by Liquid Crystal Elastomer Muscles at the Water–Air Interface

Advanced Materials Technologies, EarlyView.
Soft robots for unstructured environments require responsive, durable actuators. Liquid crystal elastomers (LCEs) provide large reversible deformations under thermal or optical stimuli. Direct ink writing enables fabrication of LCE actuators integrated with silicone, with mesogen chemistry and oligomers optimized for printable inks.

Low‐Outgassing Liquid Metal–Silicone Composites for Multifunctional Space Applications

Advanced Materials Technologies, EarlyView.
Integrating liquid metal microdroplets into a space‐grade silicone creates a multifunctional composite while preserving its inherent flexibility and low‐outgassing behavior. The composite has 11×$\times$ higher thermal conductivity while remaining thermally stable and maintaining a total mass loss of ≤$\le$ 1% under thermal vacuum testing.

A Self‐Healing Permanent Magnet Putty for Soft Robot Skins With Force Sensing and Functional Recovery

Advanced Robotics Research, EarlyView.
Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these
