Abstract

A method based on magneto-acoustic technique is developed to measure bioelectric currents non-invasively. Theoretically, vibrations of particles in the medium are produced due to the Lorentz force when oscillatory currents flow through medium in a steady magnetic field. These vibrations contain information of the bioelectric currents and can be detected by surface contact detector. An experimental setup is presented to detect the microampere level currents in saline and tissue. The results show the linear relationship between the acoustic signal and the current.
