title: Observations on blood flow related electrical impedance changes in rigid tubes.
abstract: Mammalian blood in pulsatile flow through a rigid tube has been shown to be anisotropic with regard to its electrical conductivity. When flow increases there is a rise in conductivity in the longitudinal and a fall in the radial direction. These changes are caused by flow-dependent variations in the orientation of the disk-shaped erythrocytes.
