Element with expansible relief
First Claim
1. Element with a front face with evolutive relief, said element comprising individual means for modifying the relief of the front face, arranged according to a regular pattern and control means capable of piloting separately all the individual means for modification of the relief of the element, wherein the individual modification means of the relief comprise sealed cavities filled with a product able to change volume when a predetermined temperature threshold is crossed, a deformable or mobile organ separating each cavity of the front face, and individual heating means for the product contained in each cavity, where the heating means are heating organs piloted by an electric current and the control means are connected to these heating organs by electrical conductors with a matrix layout.

Abstract
An element (10) comprises sealed cavities (24) arranged according to a regular pattern. Each cavity (24) contains a product such as a wax which changes in volume, in reversible fashion, when a given temperature threshold is crossed, together with an individual heating organ (26). The cavities (24) are separated from the front face (10a) of the element by a mobile or deformable organ (38). A separate piloting for each of the heating organs (26) makes it possible to make the relief of the front face (10a) of the element evolve in controlled fashion. Such an element can be used to re-transcribe, in relief, tactile (visually handicapped) or visual information.
