ABSTRACT
Objective To design an instrument that can provide a series of pulse to stimulate cell by means of external electric field, the structure and function of organism can retrieve. Methods AVR MCU, produced by America ATMEL Co., is used as the core of the system. The program has been developed to adjust three pulse's parameters, including amplitude, frequency and pulse duration. The cooperation between DAC and OP completes the transformation from monopole pulse to bipolar pulse. The booster PB50 amplifies the current and voltage of the output. Results The Stimulator can provide bipolar pulse, amplitude: up to ?40V, frequency: 0.01Hz -10Hz, pulse duration: 0.4ms -24ms. Conclusion Cooperating with special electrode board, the instrument can provide effective electric field for cell simulating. At present the instrument has been used in the research of the endothelial progenitor cell.
