摘要
电刺激在视觉、听觉、触觉以及肌肉功能的恢复与重建方面起到了重要的作用，如何设计一种电刺激系统，来提供灵活的配置方案，产生精准的刺激脉冲，且保证刺激终端体积小，功耗低、使用方便是有待研究的重要课题，作者提出了一种基于MSP430和ZigBee模块的无线刺激系统的解决方案，该系统包括系统软件、无线刺激控制器和无线刺激终端几个部分，无线刺激控制器和刺激终端借助ZigBee实现无线通讯，在系统软件中设置的刺激参数可以实时、无线发送到刺激终端，刺激终端以MSP430微控制器为核心，控制压控恒流源电路产生双相刺激脉冲。测试表明，该脉冲的电流强度可达10mA和频率范围为1-1000Hz。本系统可以应用到不同刺激对象和刺激场合。
Electrical stimulation has played an important role of the visual, auditory, tactile, and muscle function recovery and recon- struction. How to design an electrical stimulation system, which can create accurate stimulation pulses and provide flexible configuration op- tions while small size, low power and mobilitiy are ensured, is an important issue to be studied. This paper proposed a solution used for stim- ulation system based on MSP430 and ZigBee wireless module. The system consists of system software, a wireless controller and wireless stimulator. Wireless communication is built up between the wireless controller and stimulator terminal with ZigBee module. All stimulating parameters that are configurable and visible in PC software in real time can be transmitted wirelessly to stimulator terminal. A bipolar stimu- lation pulses with controllable current intensity and wide frequency range can be output from stimulator terminal , which is built up on MSP430. Test result showed that the intensity of the current pulse is up to 10mA and pulse frequency ranges from 1Hz to 1000Hz. This system can be applied in different stimulating occasions.
