中文摘要：

功能性电刺激在神经功能失调治疗和神经损伤功能重建中具有重要的作用,植入式神经肌肉电刺激疗法已被证实对20余种神经功能失调疾病具有确切的疗效;基于这种疗法,介绍一种基于ZigBee协议的无线可植入微刺激器的电路设计,其刺激效果与微刺激器所释放电流的参数有密切关系;为了能够在生物实验中寻找到刺激效果最佳的电流参数,设计论述了一种以低功耗CC2430微控制器为核心的微刺激器方案;低功耗CC2430的ZigBee无线通信协议是无线微刺激器电路系统的关键技术,结合双相恒流源能够对特定肌肉释放不同的刺激波形、幅度与频率的刺激电流;通过调节各种关键参数,应用这种微刺激器能够生成生物实验中所需要的双相脉冲波形。

英文摘要：

Functional electrical stimulation has an important functional role in the treatment of neurological dysfunction and functional reconstruction of nerve injury,implantable nerve muscle electricity irritation therapy has been confirmed to have accurate curative effect to 20 kind of nerve functional disease.Based on this therapy,describe a kind of wireless implantable micro-stimulator based on a protocol of ZigBee.The stimulating effect of micro-stimulator is closely related to the release of the current parameters.In order to find the best stimulating current parameters in the biological experiments,the design discusses a micro-stimulation program of centering CC2430 low-power microcontroller.ZigBee wireless communication protocol in low-power CC2430 is the key technology for wireless micro-stimulator circuity,Combinating bipolar current source can release stimulation current of different waveforms,amplitude and frequenty to a particular muscle.By adjusting the various key parameters,this micro-stimulator can generate two-phase pulse needed in biological experiments.
