Abstract:
 Objective To design and develop a portable biological electrical stimulator base on array electrodes. Methods The slave computer used STM32L432KC as hardware core. A small DC-DC booster module and a bipolar voltage controlled current source of photoelectric isolation which can output current to gating electrodes through serial-parallel conversion chip and photo-couplers bidirectional thyristor were designed. The PC used human-computer interactive software in the embedded Android system developed by Eclipse. The amplitude, pulse width and frequency of stimulation current and the electrode selection plan were adjusted by a Bluetooth module, wirelessly and flexibly. Results The stimulator was capable of choosing the best stimulation sites and intensity, bringing convenience to the clinical applications and scientific researches for biological electrical stimulation. Conclusion The stimulator is worthy of clinical research and application, with the advantages of small size, good stability, low power and easy operation.
