Abstract
An electrical epidermal stimulation device for treating skin ailments having a power supply configured to provide power to the electrical epidermal stimulator, a first and second electrode configured to provide an electrical stimulus to an area of application, a wake up module configured to wake up a control module when a current flows from the first electrode to the second electrode, a voltage step generator module configured to generate a voltage, and an output drive module configured to control a direction of the voltage step to the first and second electrodes. In one embodiment, the electrical epidermal stimulation device comprises an indicator module for notifying a user that the device is functioning. In another embodiment, the voltage step generator module provides a voltage that increases and decreases in predetermined amounts to create a voltage step. In another embodiment, the direction of voltage application switches between the first and second electrodes. In another embodiment, the voltage is applied to the affected area in phases of varying frequency.
