本文描述了一种在不使用常规糊剂的情况下，从未经处理的皮肤记录心电图电位的技术的各个方面的实验。由于在没有电解糊剂的情况下遇到相对高的皮肤-电极阻抗，因此必须利用高输入阻抗放大器来采集信号。为了最大限度地减少对外部静电和电磁干扰的敏感性，高输入阻抗放大器的固有问题，缓冲放大器直接集成在电极外壳内。在测试的不同金属中，不锈钢被证明是无膏手术中最稳定的皮肤接触材料。所描述的集成电极缓冲放大器符合美国心脏协会的规范，并且应当证明其作为现有临床EKG设备中的常规糊状电极的直接替代物以及对于诸如空间任务和重症监护病房患者监测的长期应用是有用的，其中频繁注意电极是不方便的。
Experimentation regarding various aspects of a technique for recording electrocardiographic potentials from unprepared skin, without the use of conventional paste, is described. Because of the relatively high skin-to-electrode impedances encountered without electrolytic paste, high input impedance amplifiers must be utilized for acquisition of the signal. In order to minimize susceptibility to external electrostatic and electromagnetic interference, an inherent problem with high input impedance amplifiers, buffer amplifiers were incorporated directly within the electrode housing. Of the different metals tested, stainless steel proved to be the most stable skin contact material for pasteless operation. The integrated electrode-buffer amplifiers described comply with specifications of the American Heart Association and should prove useful as a direct replacement for conventional paste-type electrodes in existing clinical EKG equipment as well as for long-term applications such as space missions and intensive-care-unit patient monitoring, where frequent attention to the electrodes is inconvenient.
