The properties of 18 electrode jellies were investigated: electrical conductivity, ionic content, pH, skin irritation, and skin impedance reduction with different skin preparations, motion artifact, electrochemical noise with different electrode material, susceptibility to drying, ease of handling, and cost. There were significant differences of performance. Skin compatibility after 8 h ranged from "no irritation" to "severely irritating". A skin irritation most likely occurred with decornifying skin preparation. The specific skin impedance 24 min after the application ranged from 15 k omega . cm2 to 125 k omega . cm2. The motion artifacts differed up to 250%. All jellies produced negligible noise with Ag/AgCl and stainless steel electrodes. However, with gold and silver electrodes the noise amounted to 19 and 23 mu V. The NaCl content was correlated to the skin irritation and the impedance reduction. The impedance reduction correlated inversely to the skin compatibility and the motion artifact. Guidelines for the selection of an appropriate jelly in ergonomic long-term monitoring are given.
对18种电极凝胶的性能进行了研究：电导率、离子含量、pH值、皮肤刺激性、不同皮肤预处理后的皮肤阻抗降低情况、运动伪迹、不同电极材料的电化学噪声、干燥敏感性、操作便利性和成本。性能存在显著差异。8小时后的皮肤兼容性从“无刺激”到“严重刺激”不等。去角质皮肤预处理最有可能引起皮肤刺激。应用后24分钟的比皮肤阻抗范围为15 kΩ·cm²至125 kΩ·cm²。运动伪迹差异高达250%。所有凝胶在银/氯化银电极和不锈钢电极上产生的噪声可忽略不计。然而，使用金电极和银电极时，噪声分别为19 μV和23 μV。氯化钠含量与皮肤刺激性和阻抗降低相关。阻抗降低与皮肤兼容性和运动伪迹呈负相关。给出了在人体工程学长期监测中选择合适凝胶的指南。
