Microdevices that change their behavior in response to local chemical environments in liquids are expected to be useful for applications such as localized stimulation, transport, and sensing in natural water and biological fluids. We have previously developed an autonomous swimmer driven by bubble generation through chemical reactions. In this system, changes in the reaction field are reflected in the motion dynamics through changes in bubble generation rate and the resulting buoyancy oscillations, making it useful as a platform for reading out chemical environments as motion responses. In this study, we investigated the rise-and-sink motion of the autonomous swimmer through a mechanical model and examined its motion response to changes in the chemical environment.
