The soothing and slow movement of this transparent surface above the visitors provides the eery feeling of diving in the bottom of a shallow sea. This “breathing ceiling” is based on a new type of morphing system developed in our research lab: light, stiff, easy to manufacture and to roll.
Material: Heat-sealed TPU films
Two superimposed sheets are thermosealed along a precise labyrinthing path by a digitally controlled hot point.
The seams defines internal flat channels that will contract laterally when inflated into tubes.
When this contraction, oriented by the tubes, is not compatible, that is when some parts want to contract along different orientations, the geometrical frustration can only be solved by popping out of plane into a 3D shape. This could not have been obtained from the initial planar sheets without a lot of cutting and stitching.
Although very light, and capable of changing shape, this surface can become very stiff when inflated, and could be used at architectural scale.
