Pneumatic structure and its manufacturing method

摘要

The structure (10) includes an elastic deformable body (12) defining at least one cavity array (14, 14),Each lumen (...) has a closed contour (... 14) in at least one lumen portion. Each cavity (14) is adapted to pressurize so that the deformable body is elastically transferred from one resting structure to at least one pressure structure. In each pressurized configuration, the elastic deformable body (12) has a macro metric independent of its idle configuration. In each pressurized structure, the bending radius of the outer surface of the elastic deformation body is（Each inner cavity ((14) relative to the adjacent outer surface is twice as large as the inner cavity (() 14) adjacent to the outer surface.
