论文摘要
容易与物理系统接口的替代计算方法非常适合对这些系统的嵌入式控制。我们证明了作为微流体阀的气动电路实现的有限状态机,并使用这些控制器来指导微流体液体处理程序,例如在同一芯片上的连续稀释。这些整体式集成系统仅需要以真空源的形式在外部提供功率。可以通过用手指覆盖气动端口直接向芯片提供用户输入。显示了最多四个状态内存的状态机器,并且可以通过更改芯片中膜上的孔突击模式来完全重新编程下一州组合逻辑。这些气动计算机为物理系统的嵌入式控制展示了一个新的框架。
Alternative computing approaches that interface readily with physical systems are well suited for embedded control of those systems. We demonstrate finite state machines implemented as pneumatic circuits of microfluidic valves, and we employ these controllers to direct microfluidic liquid handling procedures such as serial dilution on the same chip. These monolithic integrated systems require only power to be supplied externally, in the form of a vacuum source. User input can be provided directly to the chip by covering pneumatic ports with a finger. State machines with up to four bits of state memory are demonstrated, and next-state combinational logic can be fully reprogrammed by changing the hole-punch pattern on a membrane in the chip. These pneumatic computers demonstrate a new framework for the embedded control of physical systems.
