Auxetic Foam Sample

Auxetic foams exhibit unique mechanical characteristics; they expand in multiple directions when stretched in one. These unusual properties can be obtained by modifying conventional foams through a compression and treatment process. A 1mm cube model and an accompanying image showcase the result of this conversion process, with a final image featuring a 3mm sample taken from a smaller region of interest. The open-cell polyurethane foam model was reconstructed from Micro CT images, while the untreated counterpart can be found here: [Conventional Foam Sample](http://example.com/foam).
