Abstract

The invention relates to an article (10) made of a shape memory composite material (12) comprising a shape memory polymer (14) and a magnetic material (16) embedded therein, said shape memory polymer (14) after thermomechanical programming being capable of undergoing at least one temperature-induced transition from a temporary shape into a permanent shape, as well as to a method for the production thereof and a method for retrieving stored shapes.It is envisaged that the article (10) has at least two directly or indirectly interconnected sections (18, 20) which differ by a different surface-to-volume ratio (S/V).
