    • Apparatus (20) for application to skin of a subject is provided. The apparatus includes a board (30) having a first surface and a second surface, the first surface including a plurality of ablation electrodes (41), which are adapted to be applied to the skin, and the second surface including one or more contact pads (32), each one of the contact pads electrically coupled to at least one of the ablation electrodes. The apparatus further includes one or more driving electrodes (28). An energy applicator (e.g., motor 22), coupled to the driving electrodes, is adapted to pass the driving electrodes over the contact pads. A power source (e.g., power unit 102) is adapted to drive a current from the driving electrodes, to the contact pads, and to the ablation electrodes. The current is capable of ablating at least a portion of stratum corneum of the skin in a vicinity of the ablation electrodes, so as to facilitate transdermal transport of a substance.
    • 提供了用于受试者皮肤的装置(20)。 所述装置包括具有第一表面和第二表面的板(30),所述第一表面包括适于施加到皮肤的多个消融电极(41),所述第二表面包括一个或多个接触垫 (32),所述接触垫中的每一个电耦合到所述消融电极中的至少一个。 该装置还包括一个或多个驱动电极(28)。 耦合到驱动电极的能量施加器(例如,马达22)适于使驱动电极穿过接触垫。 电源(例如,功率单元102)适于驱动来自驱动电极,接触焊盘和消融电极的电流。 该电流能够在消融电极附近烧蚀皮肤的角质层的至少一部分,以促进物质的透皮转运。
