Disclosed is an electrically-driven skin stimulation module for forming a relatively high potential difference between power terminals of different polarities without a voltage booster circuit to make a lot of current flow through human skin such that function of iontophoresis may be remarkably improved. The module includes: a base including power terminals of different polarities formed on a side to drive the a vibrator and connected to each other through human skin as a conductor the (a) vibrator installed on at least one side of the base a driving unit installed in the base and including a rotary shaft for providing a driving force to the vibrator and a coil interposing the rotary shaft therein a driving switch installed at a power input end of the driving unit to switch on/off a power supply of the driving unit a controller controlling the switching on/off of the driving switch to control operating state of the driving unit and vibration state of the vibrator according to the operation of the driving unit and an induced electromotive force processor including an input end connected between the driving switch and the driving unit in parallel and making electric energy generated from the coil around the rotary shaft when the driving is idle by the switching off of the driving switch flow to an output end of the driving unit.本發明係揭露一種電驅動皮膚刺激模組,其無須增壓電路,而得用以在不同極性的電源端子間形成相對高電位差以產生許多電流流經人類皮膚,使得電離子透入療法(Iontophoresis)的作用可以顯著地改善。該模組包括:一基座,包含被形成在一側之不同極性的電源端子,以驅動一振動器且經由作為一導體的人類皮膚而彼此連接;該振動器,係安裝於該基座的至少一側上;一驅動單元,係安裝於該基座內,且包含一旋轉軸以用於提供一驅動力至該振動器與插入至該旋轉軸的一線圈(coil);一驅動開關,係安裝於該驅動單元的一電源輸入端以開啟/關閉該驅動單元的一電源供應;一控制器,其根據該驅動單元的操作來控制該開關的開啟/關閉,以控制該驅動單元的操作狀態以及該振動器的振動狀態;以及一感應電動勢處理器,其包含一輸入端,係平行連接於該驅動開關與該驅動單元之間,且當該驅動藉由流至該驅動單元的一輸出端之驅動開關為關閉而閒置時,從圍繞該旋轉軸的線圈產生電能。100‧‧‧電驅動皮膚刺激模組110‧‧‧基座120‧‧‧振動器130‧‧‧驅動單元150‧‧‧控制器170‧‧‧電池
