ABSTRACT:
An improved inductive plethysmography sensor involving a conductor having alternating active and inactive segments. The active segments preferably have a narrow diamond shape which minimizes the possibility of artifact. Because of the conductor design, the sensors can be placed completely about the chest and abdomen with any overlap arranged so that active segments overlap inactive segments.
