Abstract:At present, electroencephalogram (EEG) and electrocardiogram (EKG) recording requires contact electrodes
that are inconvenient and time-consuming to apply. Emerging technology based on non-contact electrodes may alter the
way such data are gathered in clinical, field and research settings. A number of investigators have demonstrated that clinical-
grade EKG and EEG tracings can be obtained using electrodes that make no direct contact with the body. Using noncontact
electrodes, an EKG can be taken from outside a person’s clothing. The data can be transmitted wirelessly and
stored in a cell phone. This technology is the basis of a number of patents and patents pending. It may also lead to new
devices such as a whole body electromagnetic scanner, with potential applications in medicine, anthropology, agriculture,
geophysics and nutrition.
