Abstract

The invention discloses a high-precision transcranial direct current stimulation device and a control method thereof, and relates to the technical field of medical equipment, and the device comprises an electrode array module, a current output control module, a feedback control system module, a positioning and stimulation area selection module, and a data recording and analysis module. The electrode array module is used for outputting current; the current output control module is used for adjusting the intensity, the stimulation duration and the stimulation mode of the output current of the electrode array module; and the feedback control system module is used for monitoring physiological and cognitive feedback of the user so as to control the current output control module. The electrodes in the electrode array module form an annular array, a high-density current focusing area is formed, high-density current can be output, and current stimulation can be output to a stimulation area more intensively; through the feedback control system module, cognitive feedback of a user can be responded in time, stimulation of output current is adjusted, and the accuracy of stimulation parameters can be improved.
