An Ultrasonic Microrobot Enabling Ultrafast Bidirectional Navigation in Confined Tubular Environments

Highlights An ultrasonic microrobot achieves bidirectional high-speed locomotion (81 cm s−1) in micro-pipes via frequency modulation. MEMS-fabricated ultrathin piezoelectric composite film enables rapid navigation within confined pipeline (4 mm height), slope climbing (24.25°), and notable load-carr...
