Technology of electrical impedance measurement and electrical impedance tomography has been studied for several decades by our research group. In this paper, some applications of us were introduced in research fields as healthcare, psychology and intensive care.
A new method for extracting respiratory rate from electrical impedance measured on the arms is presented. The method requires application of only four electrodes to the subject's arms and is suitable to be used in a portable respiratory rate monitor and decision making systems. Set-Membership filtering is used to reduce the effect of motion artifact on the signal.
