Abstract
A rigid band electrode system is described which facilitates location of the recording electrodes of a tetrapolar impedance plethysmograph used for measuring pulsations of blood in a finger segment. The electrodes can be relocated accurately, and the volume of the finger segment under study can be precisely defined. The new system ensures good electrical contact and minimizes movement artifacts in the plethysmograph trace by holding the finger segment in a firm position.
