Arthropod‐Inspired Miniature Modular Vibration Direct‐Drive Robot With Untethered Locomotion

Advanced Science, EarlyView.
This work presents an arthropod‐inspired untethered miniature modular vibration direct‐drive robot. By utilizing standardized driving units and nested locking interfaces, on‐demand reconfiguration into quadruped, hexapod, octopod, and circular morphologies is achieved.

Shear‐Mode Direct Piezoelectric Response of Ferroelectric Nematic Liquid Crystals

Advanced Science, EarlyView.
Periodic shear‐induced electric current measurements are reported on two archetypic ferroelectric nematic liquid crystal compounds. From the temperature, frequency and shear angle dependent results of the first and second harmonic current signals together with temperature and oscillatory rheology measurements, the effective piezoelectric coupling ...

An Injectable and Self‐Reinforced Piezoelectric Hydrogel for Irregular Bone Defects Regeneration: Dynamic Epigenetic Regulation Approach

Advanced Science, EarlyView.
An injectable and self‐reinforcing RSF‐based piezoelectric hydrogel conforms to irregular bone defects and progressively strengthens in situ, overcoming the trade‐off between injectability and mechanical stability. Mechanical loading generates bioelectrical cues that promote P300‐mediated H3K9 acetylation and upregulate PTH1R expression, thereby ...

Large Electrostrain and High Optical Transmittance via Oxygen Octahedron Rotation Disordering in KNN Ceramics

Advanced Science, EarlyView.
Chemical disorder engineering reconfigures BO6 oxygen‐octahedron rotations in lead‐free K0.5Na0.5NbO3 ceramics from local ordering into a random distribution, dissolving the longstanding trade‐off between optical transparency and electromechanical strain.
