Περίληψη: The responsive behaviour of non-living tissues under an external stimulus is determined by the anisotropic, non-homogenous and multilayer characteristics of their structure. The development of responsive materials that alter their shapes in response to environmental stimuli is of great importance. Most of the proposed materials or structures are fabricated as 2D plane surfaces and alter their geometry to become 3D complex structures in response to a stimulus. In this study, we present the fabrication process and the transformation mechanisms of multilayer materials that have been formed to have a 3D initial shape and alter their geometry to form 2D shapes or other complex 3D shapes without the use of complex forming tools. The shape change is reversible under a temperature stimulus. This approach uses the multilayer structure, the anisotropic thermo-mechanical properties of the different materials, and the variable modulus of elasticity of the polymeric materials in order to create responsive 3D complex geometries at room temperature. Finally, we demonstrate a complex structure that alters its shape from a 3D shape to a 2D or o a different 3D shape and we study the curvature and the occurred failures during the fabrication process.
