"Chemistry Meets Technology: The Molecular Flip-Flop Controlled by Lasers"
Originally Published 1 year ago — by Hackaday
Markus Bindhammer has created a unique flip-flop using photochromic molecular switch, lasers, and chemicals, demonstrating the reversible color-changing property of photochromism. The setup involves two laser modules, an Arduino, and a glass cuvette filled with a photochromic chemical mixed with clear epoxy resin. The spot changes color when exposed to UV light and can be reverted back with a red laser or heat. This innovative use of chemistry and optics showcases the potential for creating optical logic components.
