Microfluidic sensors based on memristive circuits synchronization

In the recent years, two-phase microfluidics has contributed to various scientific areas such as chemistry, biology and medicine. In particular, two-phase flows, obtained from two immiscible fluids or a mix of fluid and microparticles, gained attention for their possible application in implementing logic gates and programmable devices. Moreover, their behavior in networks of microchannels is still not well studied, even if some experimental results are presented in literature but far from well-established framework that can drive to the flow control. Recently, the dynamics of two-phase microfluidic setups has been characterized by means of chaos synchronization obtaining a behavioral model of the bubble flow. Starting from these results, in this contribution the possibility to model the bubble flow behavior in a two-phase microfluidic with a simple nonlinear two-element circuit composed by a capacitor and a memristive device. The circuit is able to synchronize its dynamics to the microfluidic setup behavior, therefore acting as a qualitative sensor of the hydrodynamic regime.
