Bio‐Inspired Gradient Heterogeneous Architectures for Ultrasensitive and Robust Strain Sensors via Programmable Crack Engineering

Advanced Science, EarlyView.
Inspired by the insect campaniform sensillum, a heterogeneous bilayer strain sensor is developed based on a unique impedance mismatch and three‐dimensional structural dynamic percolation strategy. The sensor enables real‐time multi‐joint teleoperation of three joints and the gripper using a six‐degree‐of‐freedom robotic‐arm platform.

Syntheses, X‐ray Crystal Structures, and Raman Spectra of Self‐Assembled XeO3 Chain and Network Complexes of Polytopic sp2‐ and sp3‐Nitrogen Bases

Angewandte Chemie, EarlyView.
Supramolecular 1‐D, 2‐D, and 3‐D networks comprised of ‐(‐O═Xe(O2)‐‐)‐∞ and ‐(‐Xe(O2)O‐‐‐HO(H)‐‐)‐∞ chains coordinated to polytopic N‐base ligands were synthesized and structurally characterized by X‐ray crystallography. Their Xe‐‐‐N and Xe‐‐‐O bonds are characteristic of σ–hole bonds in which the nucleophilic Lewis base sites of the N‐ligands, H2O ...

Atomic Scale Control of Thermal Conductivity in LaMnO3/SrMnO3 Superlattices

Advanced Electronic Materials, EarlyView.
Interface‐dominated cross‐plane thermal transport in [(LaMnO3)m/(SrMnO3)n]10 superlattices can be controlled by the octahedral rotation/tilt angle φOOR of the MnO6 octahedra, which as well is controlled by the “m/n” ratio. ABSTRACT We report atomic scale structure and phonon thermal transport in (LaMnO3)m/(SrMnO3)n/SrTiO3(100) superlattices (LMO/SMO ...

Vertically Weft‐Knitted Smart Kinesiotapes for High‐Sensitivity, Low‐Drift Textile Strain Sensing in Close‐to‐Body Motion Monitoring

Advanced Electronic Materials, EarlyView.
Textile architecture is shown to govern the electromechanical response of embroidered and weft‐knitted strain sensors. Sensor geometry, sensing‐path length, and yarn orientation strongly affect resistance and sensing behavior. Vertical weft‐knitted structures provide the most distinct cyclic response and high sensitivity, highlighting their potential ...
