Logic gates based on chemical wave propagation in geometrically constrained excitable media are demonstrated in a Belousov-Zhabotinsky membrane system. The catalyst of the reaction is printed in specific predetermined patterns with geometries designed to provide various logic operations. Computational studies of the serial coupling of elements to form multicomponent gates and general chemical wave circuitry are presented.
