在这里, 我们提出了一个新的设计的注射器泵系统的闭环压力控制。这是通过集成一个 3 d-打印注射器泵与压阻式压力传感器和开放源码微控制器。通过采用 PID 控制器, 能够精确控制进气压力, 提供快速响应时间, 同时保持设定点的稳定性。
许多使用微流控器件的实验都需要精确的射流控制, 并能开发出具有良好特征的层流剖面。一个稳定的流量剖面很重要的例子包括探索时间...

微流控工具已成为科学家在生物和化学研究的有用。由于体积利用率低, 快速测量能力和明确的流量剖面, 微流体在基因组和蛋白质研究、高通量筛选、医学诊断、纳米技术和单细胞分析1,2,3,4。此外, 微流控装置设计的灵活性容易使基础科学研究, 如调查细菌菌落的时空动态5。
许多类型的流体喷射系统已经开发, 以准确地提供流到微流控设备。这种喷射系统的例子包括蠕动和循环泵6、压力控制器系统7和注射器泵8。这些注射系统, 包括注射器泵, 通常由昂贵的精密工程部件组成。通过闭环反馈控制输出流中的压力, 增加这些系统的成本。作为回应, 我们以前开发了一个健壮的, 低成本的注射器泵系统, 使用闭环反馈控制, 以调节输出流量压力。采用闭环压力控制, 对昂贵的精密工程部件的需求被废止9。
可负担得起的 3 d 打印硬件和相关开源软件的显著增长组合使得微流控设备的设计和制造越来越多地从各种学科10的研究人员那里获得。然而, 用于通过这些设备驱动流体的系统仍然很昂贵。为了满足对低成本流体控制系统的需求, 我们开发了一个可以由实验室的研究人员制作的设计, 只需要少量的装配步骤。尽管它的成本低且简单, 但该系统可以提供精确的流量控制, 并提供了一种替代商用, 闭环注射器泵系统, 这可能是令人望而却步的昂贵。
在这里, 我们为我们开发的闭环控制注射器泵系统的建造和使用提供了协议 (图 1)。流体处理系统由以前的研究11、单片机和压阻式压力传感器所启发的物理注射器泵组成。当用比例积分-导数 (PID) 控制器组装和编程时, 系统能够向微流控装置提供良好的受控压力驱动流。这为高成本商业产品提供了低成本和灵活的替代方案, 使更广泛的研究人员能够在工作中使用微流体。
