Adaptive Biarticular Exosuit Assistance for Faster and More Efficient Walking

IEEE Transactions on Neural Systems and Rehabilitation Engineering
This study presents an adaptive biarticular thigh exosuit (BATEX) that enhances walking efficiency and speed through bioinspired actuation and a self-tuned, ground reaction force (GRF)-driven controller. The BATEX employs Force-Modulated Compliance (FMC)

Modeling Dislocation Cutting of γ′ Precipitates in Ni‐Base Superalloys: Linking Atomistic and Dislocation Dynamics Simulations

Advanced Engineering Materials, EarlyView.
Dislocation cutting of γ′ precipitates in Ni‐based superalloys is investigated by linking atomistic simulations with discrete dislocation dynamics. The critical cutting stress is shown to be governed by the antiphase boundary energy, while line tension effects promote edge‐preferred cutting.

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

Advanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Robust and stable locomotion over compliant terrains: application to lower-limb prostheses and bipedal robots [PDF]

Artemiadis, PanagiotisOver 2 million Americans are currently living with amputation, primarily of the lower limb. Although powered lower-limb prostheses manage to restore functional mobility and adapt to different speeds, conditions, and rigid terrains ...

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

Advanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...
