摘　　要：一种普通电极与前置放大电路结合起来的有源电极,该电极对噪声和干扰有很强的抑制能力,并有很好的信噪比,很适合于作生物电弱信号检测。This paper introduces an active electrode of preamplifier with ordinary electrode. It has the depression-ability to noise and interference , and more high signal/noise ratio about this electrode, It is fit for the detection of poor signal of bioelectricity.

关 键 词：有源电极 表面肌电信号 噪声 干扰
