Potential signal acquisition method and implantable nerve stimulator

The invention provides a potential signal acquisition method and an implantable nerve stimulator. The method comprises the following steps: outputting a pulse stimulation signal to a stimulation target; after the stimulation pulse of the pulse stimulation signal is finished, carrying out passive charge balance on the stimulation target; and after the passive charge balance is finished and before the next stimulation pulse is started, acquiring a potential signal of the target spot. 本公开提供一种电位信号采集方法及植入式神经刺激器，其中方法包括：向刺激靶点输出脉冲刺激信号；在所述脉冲刺激信号的刺激脉冲结束后，对所述刺激靶点进行被动电荷平衡；在所述被动电荷平衡结束后、下一刺激脉冲开始前，采集目标靶点的电位信号。
