| This study is focused on obtaining intelligent structures manufactured from shape memory polymers possessing the ability to change their geometry in successive or `step-by-step¿ actions. This objective has been reached by changing the conventionally used shape memory activation systems (heating resistance, laser or induction heating). The solution set out consists in using Peltier cells as a heating system capable of heating (and activating) a specific zone of the device in the first activation, while the opposite zone keeps its original geometry. By carefully reversing the polarity of the electrical supply to the Peltier cell, in the second activation, the as yet unchanged zone is activated while the already changed zone in the first activation remains unaltered. We have described the criteria for the selection, calibration and design of this alternative heating (activation) system based on the thermoelectric effect, together with the development of different `proof of concept¿ prototypes that have enabled us to validate the concepts put forward, as well as suggest future improvements for `intelligent¿ shape memory polymer-based devices | |
