标题： Oscillating chemical reactions enable communication between responsive hydrogels

摘要： 响应性水凝胶可以感知环境刺激，并通过排出水分和改变形状作为执行器做出反应。 在本文中，我们提出了理论来证明，响应性水凝胶组也可以通过利用弹性变形对化学反应动力学的影响相互沟通。 具体来说，我们考虑一个由两个空间分离的化学响应性水凝胶组成的系统，这些水凝胶悬浮在发生Belousov-Zhabotinsky（BZ）型反应的溶液中。 通过求解溶剂通过多孔弹性网络的传输以及化学动力学的水凝胶动力学，我们展示了每个水凝胶的周期性膨胀-收缩振荡如何变得耦合，以及如何通过对手动水凝胶的机械操作来影响局部（从而全局）振荡频率，从而从一个水凝胶向另一个水凝胶发送信号。 显示英文摘要

摘要： Responsive hydrogels can sense environmental stimuli and respond as actuators by expelling water and changing shape. In this article, we develop theory to demonstrate that groups of responsive hydrogels can also communicate with each other, by utilising the effect of elastic deformation on chemical reaction dynamics. Specifically, we consider a system of two spatially-separated chemically responsive hydrogels suspended in a solution in which a Belousov-Zhabotinsky (BZ)-type reaction occurs. Solving for the gel dynamics with the transport of solvent through the poroelastic network and the chemical kinetics, we show how the periodic swelling-deswelling oscillations of each gel can become coupled, and how this coupling can be exploited to send signals from one gel to the other via mechanical manipulation of the sender that affect the local (and thus global) frequency of oscillation.
