TacScope: A Miniaturized Vision‐Based Tactile Sensor for Surgical Applications

open access: yesAdvanced Robotics Research, EarlyView.
TacScope is a compact, vision‐based tactile sensor designed for robot‐assisted surgery. By leveraging a curved elastomer surface with pressure‐sensitive particle redistribution, it captures high‐resolution 3D tactile feedback. TacScope enables accurate tumor detection and shape classification beneath soft tissue phantoms, offering a scalable, low‐cost ...

Aging‐Induced Ductile‐Brittle‐Ductile Transition in High‐Entropy Alloys and its Implications

open access: yesAdvanced Science, EarlyView.
Local chemical orders (LCOs) and phase boundary (PB) engineering are key strategies for strengthening high‐entropy alloys (HEAs). However, excessive ordering induces severely localized deformation and high‐index jagged PBs hinder dislocation transmission, both impairing ductility.

Material‐Gradient Enabled Enhancement of Strength and Strain‐Hardening of Lattice Structures

open access: yesAdvanced Science, EarlyView.
This study employs material gradients in lattice structures via alloy‐controlled additive manufacturing, decoupling mechanical behavior from geometry. Gradients guide stable plastic fronts, enhancing plateau stress and energy absorption by up to 25.4%.

Ultrafine Molybdenum Wire Braided Neurointerventional Implants: Bridging Biodegradability and Neurovascular Safety for Stroke Treatment

open access: yesAdvanced Science, EarlyView.
Molybdenum (Mo), with its unique strength, uniform corrosion, and radiopacity, enables innovative biodegradable implants for transformative stroke therapy. Abstract Neurovascular implants for stroke intervention face a critical dilemma: permanent devices (e.g., nitinol stents, platinum coils) often trigger chronic inflammation and recurrence, whereas ...
