The invention provides a locomotive solid-state device and an implantable medical system having the same. The locomotive solid-state device comprises a substrate, a signal receiving unit and a micro-controller. On the substrate at least one electrode is formed, and the signal receiving unit receives a plurality of electrical signals. The micro-controller electrically controls the electrode, in which the voltage applied on each electrode according to the electrical signals received by the signal receiving unit, so that the locomotive solid-state device moves along at least one direction.
