<p>The invention concerns an element with expansible relief. Said element (10) comprises sealed cavities (24) distributed in a uniform system. Each cavity (24) contains a product such as wax which varies in volume reversibly when a given temperature threshold is exceeded, and an individual heating member (26). The cavities (24) are separated from the front face (10a) of the element by a mobile or deformable member (38). A separate control of each of the heating members (26) enables a controlled development of the relief of the front face (10a) of the element. Such an element can be used for three-dimensional transcription of tactile (for visually disabled people) or visual data.</p> |
