And a method for estimating the in vivo device potential using a multi-point surface electrode impedance switching type

摘要

Estimator in vivo potential, a device provided with (2), the measuring electrode (EM) and the ground electrode (EG) (1), measuring body part, The ground electrode and the measuring electrode is arranged at different positions on the surface of the living body (5), The measurement unit is disposed between the ground electrode and the measuring electrode, and a (VR) capable of changing the impedance switching device and the resistance value, Each time it is set to a predetermined value the impedance of the impedance switching device, through the measurement portion, the body portion is recorded by measuring the potential of the measuring electrode, Using the potentials recorded, the main unit calculates the potential and the position of the signal source of the living body.
