Low-powered and accelerative synchronization in the coupled system of nonlinear hardware oscillators

In a diffusively coupled system using a mathematical model of heart muscle, an acceleration phenomenon has been reported in which the oscillation period after coupling becomes smaller than the intrinsic period prior to coupling. In the present research, an acceleration phenomenon is observed in a coupled system of an electronic circuit model. Also, by using an electronic circuit simulator, the conditions causing acceleration in a coupled system are studied. The power consumption of a coupled system is numerically derived. It is found that the power consumption can decrease when the acceleration phenomenon takes place. Heart muscle cells not only accelerate the oscillation (or increase the number of oscillations) by mutual coupling but also reduce the power (or energy) consumption at the same time. It is suggested that efficient information transmission may be carried out with less energy overall. © 2004 Wiley Periodicals, Inc.
