An olfactory patch comprises a well (6) formed by a reservoir layer (2), the well sandwiched between a barrier layer (3) and a permeable layer (4). The permeable layer defines a pathway for olfactory fluid flow from the well (6) (A, Figure 1 ). The flow of the olfactory may be commenced by an initiator mechanism, and may control or terminate the flow of olfactory. The olfactory patch may utilise any olfactory fluid or combination of fluids within the same patch. The patch may utilise olfactory fluid which may provide any type of functionality from fragrance to drug delivery. The olfactory patch has applications in multiple environments and surfaces such as jewellery or fashion accessories or objects of therapeutic value. Micro electro-mechanical devices may be used within the patch system which utilise fuel cell technology to control olfactory flow or to provide any other functionality. |
