The bottom layer of the casted silicone is 1/8 inch thick, and the top layer is 1/16 inch thick. When inflated, this difference in thickness causes the chambers to bulge out and bend. The geometry is designed to be symmetric, with two sets of chambers on each side. One set of chambers is arranged vertically and the other set is arranged horizontally, so that they embrace the shape of the face completely to create a strong tactile feeling when inflated.
Another design is for the preys. It stretches horizontally and bends inward to embrace the eyes.
