Abstract

Un aspect de certains modes de réalisation de la présente invention concerne un patch comprenant un mécanisme de régénération d'une commande de parfum et/ou d'odeur. Par exemple, le patch peut comporter de multiples réservoirs de parfum et/ou solvant. Éventuellement, lorsqu'un réservoir est épuisé un autre peut être activé. Éventuellement, le patch est efficace sans que les produits chimiques odorants et/ou le solvant entrent en contact avec l'utilisateur. Dans certains modes de réalisation, un patch cutané comprend une zone de volatilisation et/ou un réservoir contenant un parfum et/ou un solvant volatil. Éventuellement, le patch est activé après avoir été placé sur la peau. Par exemple, le patch peut être activé par déplacement du solvant et/ou du parfum vers la zone de volatilisation.
