Abstract:
Drawing inspiration from plant and animal vasculature, our presentation will focus on flow networks that incorporate valves with negative differential resistance, meaning that the flow decreases as the pressure difference increases. We will describe a phenomenological model for nonlinear flow networks of any topology, including nonlinear resistors and the capability for internal accumulation/depletion of volume. This model exhibits a wide range of complex phenomena, such as self-sustained oscillations, excitability, and memory effects. Specifically, we will discuss the fluidic memristor, a system whose global resistance can be tuned through the applied pressure protocol, leading to a resistance that depends on the past. We will also show our experimental validation of this system.
