提出了一种新颖、廉价、基于聚合物的阀门方法，该方法将止回阀的整流特性与主动控制向前（打开）方向的流量的可能性相结合。带有切口的弹性膜被夹在两个刚性聚合物板之间，当向前施加压力时，弹性膜会膨胀，从而允许流体通过。在向后的方向上，膜不可能膨胀并且阻止了流动。由于膜的弹性，改变夹紧力会影响膜的膨胀能力，从而能够控制流量。
A novel, inexpensive, polymer-based valve approach is presented that offers the combination of a check valve's rectifying properties with the possibility to actively control the flow rate in the forward (open) direction. An elastic membrane with an incision is clamped between two rigid polymer plates and expands when pressure is applied in the forward direction allowing fluid to pass. In the backward direction, expansion of the membrane is not possible and flow is prevented. Varying the clamping force influences the expansion capability of the membrane due to its elasticity and thus enables control of the flow rate.
