We report synchronization of Mercury Beating Heart (MBH) oscillators using the environmental coupling mechanism. This mechanism involves interaction of the oscillators with a common medium/environment such that the oscillators do not interact among themselves. In the present work, we chose a modified MBH system as the common environment. In the absence of coupling, this modified system does not exhibit self sustained oscillations. It was observed that, as a result of the coupling of the MBH oscillators with this common environment, the electrical and the mechanical activities of both the oscillators synchronized simultaneously. Experimental results indicate the emergence of both lag and the complete synchronization in the MBH oscillators. Simulations of the phase oscillators were carried out in order to better understand the experimental observations.
我们报告了利用环境耦合机制实现水星跳动心脏（MBH）振荡器的同步。这种机制涉及振荡器与共同介质/环境的相互作用，使得振荡器之间不相互作用。在本工作中，我们选择了一个改进的MBH系统作为共同环境。在没有耦合的情况下，这个改进系统不会表现出自持续振荡。据观察，由于MBH振荡器与这个共同环境的耦合，两个振荡器的电活动和机械活动同时同步。实验结果表明MBH振荡器中出现了滞后和完全同步现象。为了更好地理解实验观察结果，对相位振荡器进行了模拟。
