Dynamic Current Routing in Conductive Liquid Crystal Elastomers for Complex Deformation Actuators

Advanced Materials Technologies, EarlyView.
This work introduces a novel actuation control strategy in which electrical stimulation generates localized Joule heating in conductive liquid crystal elastomer (LCE) surfaces, enabling complex 3D deformations from a single homogeneous surface without preprogramming.

Active nematics in corrugated channels

Soft Matter
In corrugated channels, active nematics transition from counter-rotating swirls to coherent flows. Swirling structures in the corrugations facilitate slip, lowering the critical activity needed for the transition.

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Liquid Crystalline Elastomers in Soft Robotics: Assessing Promise and Limitations

Advanced Robotics Research, EarlyView.
Liquid crystalline elastomers (LCEs) are programmable soft materials that undergo large, anisotropic deformation in response to external stimuli. Their molecular alignment encodes directional actuation in a monolithic structure, making them long‐standing candidates for soft robotic systems.

Modeling active nematics via the nematic locking principle

Soft Matter
We model microtubule-based active nematics based on the foundational idea that an initial curve following the director field must continue to follow the director field as it evolves. The resulting model shows improved agreement with experiment.

Temperature of an active nematic [PDF]

Physical Review Research
We employ a hydrodynamic framework for active matter coupled to an environment to study the local temperature of an active nematic, assuming proximity to thermal equilibrium. We show that, due to the mechanosensitivity of fuel consumption, linearized temperature correlations in a homogeneous active nematic steady state remain unaffected by activity ...

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators

Advanced Robotics Research, EarlyView.
We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.

Advances in Electroactive Liquid Crystal Elastomers for Intelligent Robotics and Electronics

Advanced Robotics Research, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) integrate molecular anisotropy with electrical functionality to enable programmable actuation and reconfigurable electronics. This review classifies eLCEs into robotic actuators and adaptive electronics, summarizes key actuation mechanisms, and highlights fabrication strategies that bridge materials to ...

Aspects of the density field in an active nematic [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014
Active nematics are conceptually the simplest orientationally ordered phase of self-driven particles, but have proved to be a perennial source of surprises. We show here through numerical solution of coarse-grained equations for the order parameter and density that the growth of the active nematic phase from the isotropic phase is ...
