Boolean Gates Based on Liquid Marbles

Abstract

Liquid Marbles are liquid droplets encapsulated by hydrophobic powder particles. They offer an efficient approach to handling liquids due to their non-wetting nature. In this work, starting from the interaction gate proposed in the literature, we describe how the logic gates AND, XOR, OR, NOT, NAND, and NOR could be realized. Given the irreversibility and non-conservativeness of classical gates, we also discuss a possible implementation of the Toffoli gate, a reversible gate, and of the Fredkin gate, a reversible and conservative gate.
