Abstract
A transcranial direct current stimulation (tDCS) apparatus includes a stimulation unit, a control unit, and an input/output (I/O) unit. The stimulation unit includes a power-supply unit to supply power for electrical stimulation corresponding to a control signal received from the control unit, and a plurality of stimulation electrodes, each of which has a hydrogel patch, to provide electrical stimulation to a living body upon receiving the power from the power-supply unit. The control unit is configured to control an on/off function of the power-supply unit such that the power-supply unit is turned on or off according to the amount of power applied to the stimulation electrodes and a time period during which the power is supplied or not supplied.
