Abstract

This paper presents a programmable chemical processor using a 5x5 array of cells filled with a Belousov-Zhabotinsky (BZ) reaction. Each cell can be individually switched 'on' or 'off', resulting in over 2.9 × 10¹⁷ chemical states detectable via image processing. The interconnected BZ reactions demonstrate chemically encoded and addressable memory, and a chemical autoencoder for pattern recognition achieving one million operations per second.
