Neurons and cardiac cells transmit the physiological information by propagating the action potentials. We proposed an electronic circuit oscillator model especially for the cardiac cells. The diffusively coupled system of these hardware models shows the acceleration phenomena, whose periods get shorter than the period of each isolated system. In this report, we investigated, using the hardware models, the needed power consumption to cause the acceleration phenomena. As a result, we found that the power consumption could be reduced through the coupling of the isolated systems, though the acceleration phenomena were observed.
