Abstract Micro/nanomotors (MNMs) are highly versatile small‐scale devices capable of converting external energy inputs into active motion. Among the various sources, light stands out due to its abundance and ability provide spatiotemporal control. However, effectiveness light‐driven motion in complex environments, such as biological tissues or turbid water, is often limited by scattering reduced penetration. To overcome these challenges, recent innovations have integrated light‐based actuation with other stimuli—such magnetic, acoustic, electrical fields—broadening functional range control MNMs. This review highlights cutting‐edge developments dual‐energy powered MNMs, emphasizing examples where paired secondary sources for enhanced propulsion task performance.
