METHOD OF FABRICATING SHAPE MEMORY POLYMER-BASED THREE-DIMENSIONAL DEVICES

摘要

A method of fabricating a three-dimensional geometrically complex device is provided, based on a shape memory polymer. The method includes selecting a substrate composed of a shape memory polymer. A filling material is deposited in or on a planar surface of the substrate, thereby forming the device. The planar surface of the substrate may be in either a temporary or original shape of the substrate. Prior to the deposition of the filling material, the substrate is transformed into a first shape having a planar surface if the original shape of the substrate does not have a planar surface. The device is configured to be thermo-mechanically tunable to display a plurality of geometrically complex shapes, under a series of temperature changes and stress.
