The present invention belongs to the field of medical accessories, more precisely to the field of accessories for protection against outer conditions such as impacts, high or low temperature and similar conditions that can harm a human being. The invention relates to a personalized accessory for protection of a body part, which comprises a protective element, which fits to the shape of the excrescence, a scar or a wound, and an adjustable part to which the protective part is attached, glued, sewed or inserted, wherein the adjustable part can be stretched or in any other way adjusted to the particular body part, which has to be protected. The said accessory is manufactured in the following way: first the body part with the injury is scanned or measured in order to obtain a 3D model of the scanned or measured body part. Then the protective element is made using a 3D printer or thermoforming with an adjustable mould, wherein the finished protective element is then attached to the adjustable part.

The present invention relates to the field of 4D printing, and particularly to an electro-responsive folding and unfolding composite material for 4D printing, a method for manufacturing the same, and a method for regulating shape memory behavior thereof. In the process of layer-by-layer printing, conductive layers are embedded into a pre-designed shape memory polymer matrix through spray-coating and laser-irradiation nano-fusion welding, to manufacture a folding and unfolding structure with electro-responsive shape memory behavior. The distribution and range of heat affected zones in the electro-responsive shape memory folding and unfolding structure are controlled by adjusting the number of electric heating layers energized and the value of an energizing voltage. The speed of shape recovery and the degree of shape recovery of the structure are regulated according to a magnitude relationship between a shape recovery force F.sub.recovery and a resistance F.sub.resistance to shape recovery of the structure.
