Bio‐Inspired Artificial Ionic Mechanoreceptor
Advanced Functional Materials, EarlyView.A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

A linear hydraulic fracture with tortuosity and fluid–slip at the fluid–rock interface
Partial Differential Equations in Applied MathematicsA hydraulic fracture with tortuosity and fluid–slip at the fluid–rock interface is replaced by a two-dimensional symmetric model fracture. The mathematical model is formulated using a modified Reynolds flow law and a linear crack law.

XTRUDE: A Process‐Informed Framework for High‐Fidelity Analysis of Hydrogel Extrusion
Advanced Functional Materials, EarlyView.Extrusion performance emerges from the interplay between material properties and processing conditions. XTRUDE (eXTrusion Rheology for Understanding and Defining Extrudability) recreates the extrusion environment with in situ pressure and temperature sensing, enabling characteristic pressure signatures to quantify extrusion‐specific phenomena and ...

Advanced Functional Materials, EarlyView.Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

A model for frictional sliding instability on a heterogeneous fault
Annals of Geophysics, 1994 An instability of frictional sliding driven by tectonic stress is assumed to be the source of earthquakes. Empirical slip laws indicate that, under constant ambient conditions, friction depends on time, slip rate and slip history.

Decomposition of Velocity Gradient into Interparticle Slip and Rolling
Soils and Foundations, 1984 ABSTRACT Some of the best existing constitutive models for granular materials are based on the microkinematic assumption that the velocity gradient is a direct result of interparticle slip. For instance in the stress-dilatancy theory (Rowe, 1962, 1971) and in the double sliding, free rotating model (de Josselin de Jong, 1971, 1976, 1977 a, b) the ...
