Soft Active Electromyography Interface for Machine Learning‐Enabled Silent Speech Recognition

open access: yesAdvanced Intelligent Systems, EarlyView.
A soft, hand‐worn electromyography interface enables intent‐driven silent speech recognition without continuous facial attachment. The device integrates liquid‐metal interconnects, a transparent flexible circuit, and elastomer encapsulation with a fingertip electrode that contacts perioral muscles only on demand.

Semiconducting Covalent Organic Frameworks Based on Spin‐Delocalized Trioxotriangulene Neutral Radicals

open access: yesAngewandte Chemie, EarlyView.
Imine‐linked 2D covalent organic frameworks incorporating delocalized trioxotriangulene (TOT) neutral radicals were synthesized through complementary routes. Direct incorporation of an amine‐functionalized TOT radical yields a highly crystalline, porous framework (TOT‐COF‐H) with intrinsic semiconducting behavior (σRT = 1.2 × 10−4 S cm−1) and a narrow ...

Cooptimized Sensing and Sole Mechanics Enable Embodied‐Intelligence Design of User‐Specific Smart Footwear

open access: yesAdvanced Intelligent Systems, EarlyView.
An embodied codesign framework for smart footwear is presented, jointly tuning lattice mechanics and sensing for personalized plantar pressure monitoring. By integrating pneumatic sensing within 3D‐printed lattice soles, the system achieves accurate real‐time centre‐of‐pressure tracking with reduced sensor count and energy demand, demonstrating how ...

Microenvironmental Tuning in Isostructural Conjugated Metal–Organic Frameworks for Superior Photocatalytic H2O2 Generation

open access: yesAngewandte Chemie, EarlyView.
Two isostructural conjugated‐MOFs (Fe‐Tp and Mn‐Tp) photocatalysts were engineered with nonequivalent microenvironmental redox tuning for hydrogen peroxide production. The manganese analog engages both the oxygen reduction reaction and the water oxidation reaction while suppressing decomposition, delivering 10 487 µmol g−1 h−1 with an apparent quantum ...

Omnidirectional Shape Proprioception for Untethered Shape Memory Alloy‐Driven Soft Robotic Arms

open access: yesAdvanced Intelligent Systems, EarlyView.
A lightweight, modular soft robotic arm employs SMA actuation and a multi‐Hall‐magnet sensing system to achieve accurate omnidirectional shape proprioception. Each 35 g segment enables scalable assembly, while robust proprioception supports versatile navigation and manipulation in complex, unstructured environments.

Taming a Blue Gas—Structure and Chemistry of Hexafluorothioacetone

open access: yesAngewandte Chemie International Edition, EarlyView.
Hexafluorothioacetone (1), a blue gas at r.t., was synthesized by flash vacuum pyrolysis of its cyclic dimer at 660°C. We discuss fundamental properties of elusive 1, including single‐crystal structure and nuclear magnetic resonance spectroscopy, despite its tendency to dimerize even at –74°C.

Influence of Annealing Temperature on the Thermomechanical Properties and Dimensional Stability of FFF‐Printed PET‐CF

open access: yesJournal of Applied Polymer Science, EarlyView.
Following extrusion at 265°C, components underwent a 45‐min annealing process at temperatures from 145°C to 225°C. The results show that increasing the annealing temperature elevates the onset of thermal softening, significantly enhancing thermal reliability.

Self‐Assembled Telecom Color Centers in Silicon and Their Growth Environment

open access: yesAdvanced Physics Research, EarlyView.
Influence of the growth pressure during the formation of self‐assembled color centers in silicon grown by molecular beam epitaxy at ultra‐low temperatures on the color center's photoluminescence spectral signature. The growth pressure crucially determines color center selectivity, as evidenced by G‐centers, W‐centers, and T‐centers, matrix purity, and ...
