Design and Implementation of an Electrical Stimulation Device for Modified Electroconvulsive Therapy

The modified electroconvulsive therapy is an effective method for the treatment of severe depression and some other mental and nervous system disorders. In this paper, an electrical stimulation device for modified electroconvulsive therapy is designed. The device uses STM32F103ZET6 as the main control chip, and the constant current source circuit and H-bridge drive circuit are designed to output the stimulus pulse. The serial port screen is used as the human-computer interaction medium to set the stimulation parameters and control the output of the electrical stimulator. The operation is simple and the human-computer interaction is friendly. The experimental results show that the output pulse waveform of the electric stimulation device is good and the stimulation parameters reach the set target value.
