我们通过使用粘弹性聚合物溶液作为工作流体来演示微观流体控制和记忆元件。通过利用流体的非牛顿流变性能，我们能够同时展示通量稳定剂和双稳态触发器存储器。这些电路元件类似于它们的固态电子对应物，可以用作集成微流体装置控制系统的组件。这种小型化的流体电路对电磁干扰不敏感，也可用于植入药物输送装置的医疗应用。
We demonstrate microscopic fluidic control and memory elements through the use of an aqueous viscoelastic polymer solution as a working fluid. By exploiting the fluid's non-Newtonian rheological properties, we were able to demonstrate both a flux stabilizer and a bistable flip-flop memory. These circuit elements are analogous to their solid-state electronic counterparts and could be used as components of control systems for integrated microfluidic devices. Such miniaturized fluidic circuits are insensitive to electromagnetic interference and may also find medical applications for implanted drug-delivery devices.
