Modeling of Stripe Patterns in Photosensitive Azopolymers. [PDF]
Polymers (Basel), 2020 Placed at interfaces, azobenzene-containing materials show extraordinary phenomena when subjected to external light sources. Here we model the surface changes induced by one-dimensional Gaussian light fields in thin azopolymer films. Such fields can be produced in a quickly moving film irradiated with a strongly focused laser beam or illuminating the ...

Neuromorphic Light-Responsive Organic Matter for in Materia Reservoir Computing. [PDF]
Adv MaterIn this work we show that light‐responsive adaptive organic matter can store and process information at the matter level, and emulate neuromorphic functionalities such as short term memory, long term memory and visual memory. Besides demonstrating that material dynamics can be exploited for spatio‐temporal event detection and motion perception, we show
