Smoothing Oscillatory Peristaltic Pump Flow with Bioinspired Passive Components

Pulsating flows are common in many industrial, scientific, and natural fluidic systems. However, because the oscillatory flow component disturbs, e.g., optical measurements, deposition, or industrial processes, it is rarely desired. Moreover, physiological conditions, pulsation control We explore effect of using a plant-inspired nonlinear resistor to smooth output peristaltic pump. Incorporating 3D printed millifluidic biomimetic device reduces oscillation amplitudes by 3 orders magnitude, from $100\mathrm{%}$ $0.1\mathrm{%}$ rate. This represents tenfold improvement relative purely linear resistive-capacitive approach. The observed kinetics compare well predictive model transport, allowing further development optimized fluid-handling systems driven pulsatile flow. Applications particle tracking jetting considered.
