Abstract

Shape-memory polymers are active materials with thermomechanical coupling and a high capability to recover from high levels of deformation, which, combined with their low cost and density has favoured the appearance of numerous applications, particularly those linked to the Medical Industry. In many cases, these materials are of medical standard, which increases the chances of obtaining biocompatible devices. In the last decade enormous progress has been made on many areas, regarding these materials, such as synthesis, characterization, activation, prototyping and others, aimed at improving their applicability. However, various spheres of action require additional in depth research to promote the production start-up of various shape-memory polymer-based devices that have had laboratory validation. One of these areas of improvement is linked to the activation systems of SMPs. This work sets outs the possibility of obtaining a more homogeneous heating processes for an optimal activation of the “shape-memory effect”, which promotes the geometric changes of such devices. These improvements are based on the development of net-shaped SMP structures to which silver thread is knitted for subsequent activation through Joule heating. First prototypes and trials are explained in detail, as well as the possible biomedical applications of this concept.
