Problems solved by technology

Although it may temporarily deform when worn, this type of jewelry only takes advantage of the superelastic properties of shape memory materials, so it can only be used in conditions suitable for its shape and shape retention

Embodiment Construction

[0042] The present invention will be described below with reference to certain embodiments and drawings but the invention is not limited thereto but only by the claims. Notwithstanding the permission to publish this patent application, all rights are reserved to other third parties, in particular copyright or design rights to the jewels shown in the drawings.

[0043] The present invention will be discussed by detailing the hysteresis and transition range of shape memory elements, and how the gap between the activation temperature and deactivation temperature of the device can be narrowed. In the present invention, T A and T D The difference between them is 10°C or less, preferably 7°C or less, most preferably 5°C or less. In the following method, random combinations can achieve this level. Another advantage of this embodiment is that a very compact design can be achieved. This is important in jewelry design, where any moving parts must be small enough not to spoil the art...

Abstract

With the use of shape memory elements a series of devices can be made which change shape at small changes of the environmental temperature. The devices may be composed of a shape memory element and a bias element, in such a way that the thermal hysteresis of the device becomes lower than the intrinsic thermal hysteresis of the shape memory element. The devices may be used in jewelry that is adapted to change shape or configuration when subjected to temperatures in the region of the body of a wearer.

Description

technical field [0001] The invention relates to devices incorporating shape memory elements and improvements thereto, and in particular to the use of devices worn or placed in the body in close contact with the human or animal body, such as jewellery, piercing devices or medical devices and implants. Background technique [0002] Organic and metallic materials with shape memory and / or superelasticity are well known. An article made of a material with shape memory function can be deformed from an initial thermally stable structure to a second thermally unstable structure. It can thus be said that the object has shape memory in the application of heat, it can be restored or attempted to return to an original thermally stable configuration from a thermally unstable configuration, it can also be said that it can "remember" its original shape. [0003] In many metal alloys, the ability to possess shape memory is actually a result of the fact that the alloy undergoes a reversible...
