| 摘要 |
The present invention relates to a disposable electrode for providing electrical contact with a patient's scalp or skin during routine EEG or EKG tests, as well as EEG during full sleeping period in order to record electrical brain or skin waves, which comprises an electrically conductive composition having a volume resistivity in the range of between 1000 to 1500 ohms, acting also as an adhesive to the skin or the scalp by its remoistable property. The composition comprises: (1) a partially hydrolysed polyvinyl alcohol; (2) a highly hygroscopic salt selected from an metal salt, or organic chloride salt; (3) a highly electrolytic salt, and (4) a metal powder selected from aluminium, bronze and silver. The performance of the electrode was found to be the same as those known on the market. |
