Design of Portable Transcranial Micro Current Depression Therapeutic Instrument

Transcranial micro current therapy is a technology that directly introduces the action of tiny currents on the brain by electrodes placed on the earlobe. Through the stimulation of the micro current, it can increase the alpha brain wave activity and increase the concentration of the neurotransmitter that regulates the mood. It is used in the treatment of mental diseases such as depression, anxiety, insomnia and so on. A stimulator using transcranial micro current stimulation therapy is designed, and a main control chip is used to control the constant current generator circuit. It is consistent with bipolar constant micro current required for transcranial micro current stimulation. It effectively induced the alpha brain wave which made the mood stable, and enhanced the detected alpha brain wave.
