A Tangentially Sensitive Tactile Sensor Reveals the Stick‐Slip Mechanism and Enhances Robotic Tactile Sensing

Advanced Science, EarlyView.
An ultralight, multilayer anisotropic tactile sensor—an artificial Pacinian corpuscle—exhibits ultrahigh tangential sensitivity (1022 kPa−1) and spatiotemporal sensing. It discriminates static, sliding, and rolling contacts, detects incipient stick–slip via high‑frequency signatures, and enhances robotic touch (100%/98.18% accuracy for active/passive ...

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

Advanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...
