Tri‐System Interlocking Top‐Encased Structures Enabled Highly Stable Tin‐Lead Perovskite Photodetection Arrays

open access: yesAdvanced Materials, EarlyView.
A unique tri‐system interlocking top‐encased structure is formed for tin‐lead perovskites by the introduction of novel CGA additive. The fabricated tin‐lead perovskite NIR photodetector shows an outstanding specific detectivity of 2 × 1013 Jones at 940 nm, and the integrated 64 × 64 array demonstrates clear and accurate imaging abilities.

Multi‐Mode Mechanochromic Responses from Cholesteric Liquid Crystal Elastomer Tubes of Uniform Sheath

open access: yesAdvanced Materials, EarlyView.
The structural‐colored tube is created from cholesteric liquid crystal elastomers, exhibiting uniform color changes with high strain sensitivity upon extension and inflation. The color change occurs across multiple mechanochromic modes, highlighting the influence of molecular anisotropy and tubular geometry on strain sensitivity.

Self‐Spiking Linear Neuromorphic Soft Pressure Sensor for Underwater Sensing Applications

open access: yesAdvanced Materials, EarlyView.
This study presents a novel design of a neuromorphic pressure sensor that can generate self‐spiking symmetric signals with direct event‐based encoding through the integration of magnetic spheres and alternating coil circuits. The key advantages of this work include high linearity up to 200 kPa (R2 = 0.997), self‐spiking behavior for simplified signal ...
