Abstract:
The present paper presents the results of a
study to determine the feasibility of the determination of
pulse at the wrist level using electrical impedance
measurement method. In the cross section of the hand
at wrist level the pulsating artery was modeled by a
generic unit area conductivity change. The dipole model
of the electric field change by a unit area of increased
conductivity was used for a 2D electric field simulation.
The field changes by geometry deformation and shifting
bone position in the cross section as a result of hand
motion is shown to be on the same order of magnitude as
the blood related changes. The electric simulation data
are encouraging for practical application of the method.
More research is necessary to reliably separate motion
artifacts from pulse data.
