Abstract
Abstract Body surface bioelectrical potentials are determined and recorded by use of a stationary electrode in contact with the body surface and an exploratory electrode which comprises a rotatable element, that preferably carries an electrolyte. Scanning of the body surface along a continuous path or over an area is carried out by rolling at least one exploratory electrode over the said surface, thus permitting mapping of the potentials along the line or over the area contacted by the exploratory electrode, whereby abnormalities of the skin or portions of the body under the skin may be detected.
