Abstract

The present invention relates to a transcranial electro stimulation (TES) device. Specifically, the present invention relates to a transcranial electro stimulation (TES) device including a circuit that controls a constant current by using a variable resistor. A transcranial electrical stimulation device according to one embodiment of the present invention comprises: a constant current generator including at least one constant current source which outputs a constant current; a first current control circuit connected to a first constant current source among the at least one constant current source; and a control unit. The first current control circuit comprises: a first variable resistor unit for generating a first voltage corresponding to a constant current; an operational amplifier in which a first voltage is applied to a non-inverting input terminal, and a feedback voltage is applied to an inverting input terminal; and a second variable resistor unit to which a feedback voltage is applied.
