This paper presents a new approach towards the design of paper based autonomous microfluidic devices. Autonomy in the device operation is achieved through the incorporation of mechanically actuated microfluidic switches that are versatile in their design and may be configured to be simple time triggered ON or OFF switches or more complex switches that can be timed to be in multiple states (timed ON, followed by timed OFF). These switches are self-contained and require no external power for their operation, deriving their functionality solely through stored elastic energy. This paper presents the design and fabrication of these switches as fluidic analogs of electronic transistors, and their integration into microfluidic paper based circuit demonstrating their operation as a programmable paper-based microfluidic device.

用于自主实验室纸质微型设备的纸基开关的模块化设计



本文提出了一种设计基于纸的自主微流体装置的新方法。设备操作的自主性是通过结合机械驱动的微流控开关来实现的,这些微流控开关的设计用途广泛,可以配置为简单的时间触发开或关开关,或更复杂的开关,可以定时处于多种状态(定时开) ,然后定时关闭)。这些开关是独立的,不需要外部电源即可运行,仅通过存储的弹性能量来发挥其功能。本文介绍了这些开关作为电子晶体管的流体模拟的设计和制造,以及将它们集成到微流体纸基电路中,展示了它们作为可编程纸基微流体装置的操作。
