Objective To design an electrical stimulator for epileptic rats＇ experiment based on MSP430. Methods The system utilized low power MCU MSP430F1611 and the technology as generation of bi-phase constant current stimulation. Results The output of stimulation waveform, frequency, duration and intensity were set via PC and the system was controlled via PC. Conclusion The system realized low power waste. The output of stimulation parameters is controllable and not varied with the fluctuation of impedance, thus fitting the requirement of experiment.
