Energy‐Transfer‐Driven Programmable Luminescence in Bi3+‐Eu3+ Co‐Doped Na3Ca2TaO6 Phosphors Toward Multifunctional Optical Applications

Advanced Optical Materials, EarlyView.
Energy transfer from broadband Bi3+ sensitizers to Eu3+ emitters enables composition‐, excitation‐, and temperature‐dependent luminescence in Na3Ca2TaO6. These controllable optical states support ratiometric thermometry and excitation‐selective, filter‐assisted information decoding in flexible phosphor–polydimethylsiloxane films, demonstrating how ...

Tailoring Amine Substitution in Fluorene and Dibenzothiophene: A Molecular Strategy for Ultralong Organic Phosphorescence

Advanced Optical Materials, EarlyView.
Tailored amine substitution in fluorene and dibenzothiophene derivatives enables systematic control of excited‐state properties and triplet population. Combined photophysical studies, TD‐DFT calculations and time‐resolved EPR reveal how charge‐transfer character, sulfur‐induced spin–orbit coupling and triplet manifold engineering cooperate to promote ...

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space

Advanced Robotics Research, EarlyView.
A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

A Multidirectional Textile Interface for Remote Control Using Dynamic Area‐Based Capacitance Modulation

Advanced Robotics Research, EarlyView.
Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...
