Non-oscillatory micromotors “learn” to oscillate on-the-fly from oscillating Ag micromotors

Abstract

The ability to learn new functionalities on-the-fly is highly desired for micromotors operating in a changing environment. Here, we demonstrate how non-oscillatory micromotors transform into spontaneous oscillators, superficially resembling students learning from teachers, VIA the diffusion then deposition of Ag ions that act as a speed-booster that periodically turns on.
