Abstract
The invention is directed to a device for delivering a pharmaceutically active compound or cosmetic substance to a subject comprises a flexible substrate sheet attached to an electronic controller. The controller is provided with a pair of electrical contacts on the underside thereof and is adhered to the sheet by means of a pair of strips of electrically conductive adhesive. The underside of the sheet is printed in two halves with electrically conductive ink to provide a pair of electrodes separated by an insulating barrier. A protuberance extends from each electrode and is folded onto the top of the sheet such that the contacts of the controller are adhered in electrical connection with the protuberances and thus also with the electrodes. The use of an adhesive to connect a controller in electrical communication with the electrodes enables an extremely simple construction of delivery device to be achieved.
