Abstract
The present invention relates to a multi-target electrical stimulation circuit, an electrical stimulator, and a signal output method of the electrical stimulator. The electrical stimulation circuit includes a control module, a plurality of brain wave acquisition modules and a plurality of stimulation adjustment modules. Each electrode is correspondingly provided with one brain wave acquisition module and one stimulation adjustment module, and different electrodes are used for stimulating different targets. The brain wave acquisition modules are used for acquiring brain wave signals in the corresponding electrodes and transmitting the brain wave signals to the control module. The control module is used for acquiring brain rhythm phase signals according to the received brain wave signals and outputting stimulation signals at preset waveform phase points after phase locking of the brain rhythm phase signals. The stimulation adjustment modules are used for adjusting brain wave stimulation signals output to the corresponding electrodes according to the received stimulation signals. The multi-target electrical stimulation circuit, the electrical stimulator and the signal output method provided by the present invention are beneficial for achieving electrical stimulation of a plurality of targets as well as time-locked matching of electrical stimulation of a plurality of targets.
