In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque

Advanced Science, EarlyView.
In this paper, we present a wheel‐shaped direct‐current piezoelectric generator (DC‐PG) that fundamentally overcomes these constraints by producing phase‐stable DC electricity directly from rolling motion. By embedding this system into suitcase wheels, we demonstrated a fully integrated real‐time location tracking system powered solely by mechanical ...

Beyond Cartilage‐Inspired Supramolecular Polyurethane for Adaptive Impact‐Resistant Protection with Robustness, Self‐Healing, and Recyclability

Advanced Science, EarlyView.
Cartilage‐inspired supramolecular polyurethane–urea (PU‐BAMB) elastomers are developed by integrating hierarchical hydrogen bonding and π–π stacking interactions within a dynamically reconfigurable network. This synergistic supramolecular architecture overcomes the intrinsic trade‐off between rigidity and recoverability, imparting exceptional toughness,
