Microfluidic memristive oscillators as universal logic gates for neuromorphic computing

Abstract

Conical microfluidic channels filled with electrolytes exhibit volatile memristive behavior, offering a promising platform for energy-efficient, neuromorphic computing. Here, we integrate theoretical models of these iontronic channels as additional nonlinear elements in nonlinear Shinriki-inspired oscillators and demonstrate in simulations that they exhibit alternating chaotic and non-chaotic dynamics across a broad frequency range. Exploiting this behavior, we construct XOR and NAND gates by coupling three "Memriki" oscillators, and we further realize the full set of standard logic gates through combinations of NAND gates. Our results establish a new paradigm for iontronic computing and open avenues for scalable, low-power logical operations in microfluidic and bio-inspired systems.
