An electrical stimulation apparatus is provided. The electrical stimulation apparatus includes a frame worn on a user, an electrode module including a plurality of microelectrodes covered by a single patch, one surface of the electrode module is connected to the frame and the other surface faces the user while being covered by the single patch, and a processor controlling an operation of the electrode module such that a target effect is capable of being provided to the user through electrical stimulation in a state where the frame is worn on the user.

Electrical stimulation apparatus and method for controlling same

An electrical stimulation apparatus is provided. The electrical stimulation apparatus includes an electrode module receiving current for applying electrical stimulation to a skin of a user from a current providing part, a plurality of monitoring electrodes positioned spaced apart from each other on the electrode module, the current flows from the electrode module to the plurality of monitoring electrodes, and a current monitoring part monitoring the current flowing to each of the plurality of monitoring electrodes.

Current monitoring apparatus and electrical stimulation apparatus comprising same

Provided is an electrical stimulation device. The electrical stimulation device includes a first electrode that contacts a first portion of the head of a user to apply a current to the head of the user, a second electrode that contacts a second portion that is different from the first portion of the head of the user to apply a current to the head of the user, a controller that performs a control such that polarities of the first electrode and the second electrode can be changed based on a reference comprising at least one of a reference time, a reference pH index, and a reference number of uses.

Electrical stimulation device

An electrical stimulation and bio-potential measurement device is provided. The electrical stimulation and bio-potential measurement device comprises at least one electrode module which comes into contact with the scalp of a user, a current supply unit, connected to the at least one electrode module, for supplying a current to the at least one electrode module so that the at least one electrode module can apply electrical stimulation to the user, and a signal processing unit, connected to the at least one electrode module, for processing bio-potential signals detected by the at least one electrode module, wherein the current supply unit comprises at least one switch which is arranged between the at least one electrode module and a voltage source for supplying the current.

Electrical stimulation and bio-potential measurement device

Provided are an ancillary device for an electrical stimulation device and an electrical stimulation device. The ancillary device is usable for an electrical stimulation device including at least one electrode that contacts the head of a user to apply a current to the head of a user, and includes a reverse current supplier that contacts the at least one electrode of the electrical stimulation device, and a controller that controls the reverse current supplier such that a reverse current is supplied to the at least one electrode to neutralize the at least one electrode.
