The development of autonomous microsystems capable of sustained motion is crucial for advancing applications in robotics and materials science. This study demonstrates an approach to prolonging the lifetime of Marangoni motors by utilizing a self-generated contracting mantle-siphon mechanism in a gelling droplet, achieving propulsion lifetimes 300 to 1000 times longer than conventional methods.
