A transdermal system (1) for passively releasing a substance through the skin has a reservoir comprising a storage layer (2) for the substance to be released, and a transfer device which is in contact with both the reservoir and the skin during transfer. In the transdermal system (1) there are also electrodes (4, 5) which generate a current to initialize the system and which transports the substance from the storage layer (2) into a modification layer (3) contained in the transfer device. It is also possible with this transdermal system (1) to transfer several substances through the skin. |
