In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque

open access: yesAdvanced 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 ...
