Fast, Strong Capillary Liquid Metal Muscles

Advanced Intelligent Systems, EarlyView.
Capillary liquid metal muscles (CLMMs) harness the exceptionally high and electrochemically tunable surface tension of gallium‐based liquid metals (e.g., EGaIn) to generate mechanical work. Confinement within microchannels maximizes surface‐energy conversion, enabling high force, ultrafast response (<25 ms), low‐voltage operation (<10 V), and ...

3D Closed‐Loop Navigation of Magnetic Microswimmers Using Vision‐Derived Depth Feedback

Advanced Intelligent Systems, EarlyView.
A planar magnetic microswimmer is navigated in three dimensions under a standard microscope. Image defocus supplies a real‐time depth cue, and model‐predictive control with A* planning steers the body on surfaces and in free swimming. Axial position is regulated by propulsion alone, without magnetic field gradients or extra cameras.
