An active electrode (d10 mm, t6 mm) is presented, that functions as an impedance transformer (an input impedance > 10 G omega, an output impedance < 1 omega) by means of which we can derive surface EMG without any skin preparation and paste. This electrode was compared with a conventional one, and it was ascertained that the electrode could be replaced with the conventional one, and, moreover, it was preferable because it required less preparation time, and was less affected by environmental noise.
提出了一种有源电极（直径10毫米，厚度6毫米），它作为一个阻抗变压器（输入阻抗>10 GΩ，输出阻抗<1Ω），通过它我们可以在无需任何皮肤预处理和粘贴的情况下导出表面肌电图。将该电极与传统电极进行了比较，结果表明该电极可以替代传统电极，而且更可取，因为它所需的准备时间更少，并且受环境噪声的影响更小。
