Dual‐Functionality, Bio‐Friendly Artificial Muscles for Actuation and Motion Sensing in Smart Wearable Systems

Small, EarlyView.
This work presents a biofriendly carbon nanotube yarn artificial muscle operating either as an in‐air unipolar actuator or as a self‐powered ionotronic strain sensor. Using a non‐volatile eutectogel‐derived electrolyte, the system achieves up to 2.9% contraction and 0.5 mV/% strain sensing sensitivity.

Interferometric Vector Piezoresponse Force Microscopy for Simultaneous Ferroelectric Domain and Crystallographic Orientation Mapping in Uniaxial Ferroelectric Polycrystals

Small, EarlyView.
Interferometric vector piezoresponse force microscopy is used to reconstruct crystallographic grain orientations in polycrystalline ferroelectrics directly from local electromechanical response. The approach reveals grain orientation, polarization direction, and domain structure simultaneously, establishing a pathway toward EBSD‐like orientation ...

Robotic Palpation for Spatiotemporal Arterial Pulse Quantification and Mapping Using Multilevel Microdome‐Based Soft Pressure Sensors

Small, EarlyView.
This study presents the development of multilevel pressure‐sensitive layers replicated from liquid‐metal‐based structures for optimizing soft pressure sensors in robotic palpation. This approach enhances sensitivity and range for subtle arterial displacement detection.

Mesophase Tunable Actuation of Ionic Thiol‐Acrylate Liquid Crystal Elastomers

Small, EarlyView.
Thiol‐acrylate ionic liquid crystal elastomers (iLCE) are developed with nematic and cybotactic mesophases and polydomain and monodomain genesis. The effect of genesis, mesophase, and microstructure on electroactuation was studied. ABSTRACT Electroactive polymers (EAPs) are envisioned to play a crucial role in next‐generation soft robotics for their ...

Punching shear of unbonded post‐tensioned steel fiber reinforced concrete slabs: The fiber contribution

Structural Concrete, EarlyView.
Abstract Steel fiber reinforced concrete (SFRC) enhances the flexural capacity of flat slabs and, due to its effectiveness in statically redundant bi‐dimensional elements, represents a viable alternative to conventional reinforcement. Although numerous studies have investigated the flexural behavior of SFRC slabs with and without bonded reinforcement ...
