Decreasing the Cost of Morphing in Adaptive Morphogenetic Robots
Advanced Intelligent Systems, EarlyView.Shape‐morphing propulsive limbs enhance locomotion across land‐to‐water transitions, but prior designs rely on thermally responsive components, coupling performance to environmental temperature. This study introduces a pressure‐responsive mechanism that reduces morphing energy costs, enables rapid transitions, and minimizes failure modes.

Angewandte Chemie, EarlyView.Diels–Alder bond‐crosslinked liquid crystal elastomers with low nematic‐to‐isotropic transition temperatures and high reprogrammability were developed, enabling low‐energy, self‐sustained actuators through material‐structure synergy. These actuators achieve high strain rates around 30 °C, facilitating self‐sustaining motion powered by ambient/body heat

Regulating Airflow Using Hybrid LCN for Soft Pneumatic Circuits
Advanced Intelligent Systems, EarlyView.To address more autonomous soft robots with embodied control and regulation systems, herein, a liquid crystal network‐based fluid regulator that can be manipulated through multiphysical stimuli is proposed. Aided by finite element modeling for thermal actuation, regulators are designed and incorporated into fluidic circuits and demonstrate that they ...

Azobenzene‐Oxindole Photochromic Dyads
Angewandte Chemie, EarlyView.A novel photochromic azobenzene‐oxindole dyad is reported. The combination of the two switches promotes drastic molecular geometry changes and allows for precise NMR quantification. This enables the study of the photokinetic behavior under different irradiation conditions and the discovery of a unique photokinetic relationship between the two ...

Soft Robots Proprioception Through Stretchable Laser‐Induced Graphene Strain Sensors
Advanced Intelligent Systems, EarlyView.This study demonstrates the potential of laser‐induced graphene and silicone sensors for soft pneumatic grippers’ proprioception. The sensors are thin, stretchable, mechanically transparent, and easy to integrate. Finite‐element method analysis identifies the finger's neutral bending plane and four sensor positions are tested to validate the ...

On the Definition of Chirality and Enantioselective Fields
Israel Journal of Chemistry, Volume 62, Issue 11-12, December 2022., 2022 Abstract In solid state physics, any symmetry breaking is known to be associated with emergence of an order parameter. However, the order parameter for molecular and crystal chirality, which is a consequence of parity and mirror symmetry breaking, has not been known since its discovery.

Advanced Intelligent Systems, EarlyView.A passive, tunable perching mechanism enables aerial robots to reliably perch onto smooth surfaces. The design integrates a bistable mechanism with a soft suction cup and SMA actuators for active tuning. Experiments demonstrate robust performance by adapting to varying contact speeds and surface orientation misalignments, enabling diverse perching ...
