Relaxation effect of flashing of firefly robots self-organized by entrainment phenomena in nonlinear oscillations

摘要

Relaxation system inspired by synchronized flashing of fireflies was designed. This system consists of two blinking modules named as “Cardio Pulse Module” and “Synchronous Module.” The cardio pulse module has the blinker light which synchronizes with rhythm of heartbeat. And also the synchronous module has the blinker light which synchronizes with the blinker light of cardio pulse module like a feature of entrainment phenomenon. To investigate relaxation effect of the system, electroencephalogram of subjects were recorded during their use of the system. As the result, when the synchronous module was synchronized with the cardio pulse module, power of alpha wave of brain wave was increased. These results suggest that the system shows the relaxation effect by applying synchronization such as the entrainment phenomenon to the system.
