Abstract
A NASA-developed paint-on electrode has been adapted for biomedical applications by the Research Triangle Institute. 10 g of silver flake are suspended in 10 g of Duco cement and 1 oz of acetone. This mixture may be stored indefinitely, with occasional addition of acetone for thinning. In electromyographic use, each electrode is formed by placing a small (or large) drop of mixture on the skin, letting the acetone evaporate, laying the bare end of the lead-off wire over the resulting silver spot, placing another drop of mixture over the wire, and letting the resulting “silver sandwich” dry. This process typically takes less than a minute, and the electrode will remain firmly in place for hours. This paper will discuss the properties of electromyographic signals gathered by means of these paint-on electrodes, as compared with those from hooked-wire electrodes inserted in the same muscles, and will mention the potential usefulness of these electrodes for investigating the development of speech and other motor control patterns in children.
