The position of the maximum deformation shown in Figure 9 is important for structural safety, and when exposed to dynamic loads over a long period of time, there is a high possibility of fatigue fracture due to resonance, so a periodic soundness check is required at the maximum amplitude ...
With no moving part (or fixed geometry valve) that overcome the drawback of check valve such as wear and fatigue failure, but their output pump efficiency is limited to about 19–27% [47–49] (backward flow cannot be blocked completely which is one of the biggest drawbacks in microfluidic...
