Spatially distributed chemically reacting systems under far from equilibrium conditions can give rise to waves of chemical concentration. Such waves play a major role in a variety of phenomena in living systems. Probably the most well‐characterized chemical waves are those found in the Belousov–Zhabotinsky (BZ) reaction. If one or more species in a reaction that gives rise to chemical waves is photosensitive, light can be used to control these reaction–diffusion waves and wave‐driven active gel locomotion.
