CA 2629153

An optical article that can transform from a pre-activated state of functionality to an activated state of functionality is provided. The optical article includes a radio frequency circuitry coupled to the optical article for interacting with a signal, wherein said signal comprises a thermal signal, an electrical signal, or both, and a convertible material in operative association with the radio frequency circuitry for altering the functionality of the optical article from the pre-activated state to the activated state upon interaction with the thermal energy.

L'invention concerne un article optique que l'on peut transformer d'un état pré-activé de fonctionnalité en un état activé de fonctionnalité. L'article optique comporte des circuits radiofréquences qui lui sont couplés de façon à interagir avec un signal. Ledit signal comprend un signal thermique, un signal électrique, ou les deux signaux à la fois, et un matériau transformable en association fonctionnelle avec les circuits radiofréquences, ce qui permet de modifier la fonctionnalité de l'article optique de l'état pré-activé à l'état activé dès interaction avec l'énergie thermique.
