Oligomerization‐Induced Supramolecular Glass with Superior Processability and Optical Functions
Advanced Optical Materials, EarlyView.Oligomerization‐induced supramolecular glass (BGG) is formed via a catalyst‐free melt‐quenching strategy from benzoguanamine. The in situ formation of diverse oligomers suppresses crystallization, enabling glass formation. BGG exhibits a high Tg (100.1 °C), polymer‐like modulus, and bright aggregation‐induced emission, and is readily processed into ...

Non‐Reciprocal Terahertz Topological Sensor on a Silicon Chip
Advanced Optical Materials, EarlyView.A non‐reciprocal terahertz topological sensor (NTTS) is experimentally demonstrated on a silicon valley photonic crystal chip by detecting the thickness and position changes of a polyimide membrane. The sensor exploits detuning between clockwise and counterclockwise topological cavity modes, induced by integrated magneto‐optical InSb, to achieve non ...

Topological Berry Antenna on a Silicon Chip for Terahertz Wireless Communication
Advanced Photonics Research, EarlyView.The on‐chip topological Berry antenna for 6G to Xth‐generation wireless communication is designed via integrating various Berry curvatures for an enhanced antenna aperture and radiation gain. This THz antenna has demonstrated a maximum gain of 17 dBi and chip‐to‐chip wireless communications at 20 Gbps over a distance of 15 cm.

A Quadruped Piezoelectric Ultrasonic Actuating Robot with Foot‐Leg‐Trunk‐Integrated Structure
Advanced Robotics Research, EarlyView.This study proposes a novel foot‐leg‐trunk‐integrated quadruped piezoelectric ultrasonic actuating robot with small size and lightweight. A hybrid vibration mode combining the first‐order out‐of‐plane bending vibration of the trunk and the first‐order horizontal bending vibration of driving legs is designed to generate elliptical trajectories at foot ...
