Representative images of the unconfined compression mechanical test of porcine brain tissue and synthetic substitutes on 20 mm humidified platens. (a) Porcine samples including gray and white matter, (b) hydrogel based substitute material, (c) emulsion substitute material. Unloaded position read a compression force of 0.01 N and loaded position is 40% strain condition. Bottom platen remained static while top platen did the loading movement.
