Ultrafast Untethered Levitation Device Utilized Squeeze Film for Omni‐Directional Transport
Untethered levitation device (106 g, 95 × 72 × 45 mm3) on squeeze film is generated by a piezoelectric actuator with onboard electronics (77 g). It achieves frictionless and omnidirectional movement over 1.4 and 3.0 ms−1 on horizontal and inclined surfaces respectively.

A 10‐convolutional neural network ensemble using transfer learning and layer freezing analyzes 400 Doppler‐ultrasound spectrograms to distinguish speckle, artifact, and ESs. Soft and hard voting drive performance to 96.7% accuracy and 96.5% F1, highlighting a practical route for early embolus detection and stroke‐risk mitigation.

Enhancing Microrobot Swarm Stability and Adaptation by Autonomous Field‐of‐View Planning
This work presents an adaptive cross‐field‐of‐view navigation strategy for microrobot swarms in large‐scale workspaces by integrating global path planning via A* and local replanning using optimized informed rapidly‐exploring random tree star . The hybrid approach ensures efficient and robust trajectory execution in dynamic environments, enhancing the ...
