title = "Possibility of noninvasive biocurrent measurement by ultrasonic tissue resistivity modulation",
abstract = "It can be shown that ultrasonic waves cause subtle but detectable electrical changes in tissue during their passage. In particular, tissue resistivity changes on the order of 0.01% per atmosphere of sound pressure have been measured. The present experiments show that ionically carried electric currents in tissue when exposed to moderate sound power levels yield an amplitude-modulated signal equal in frequency to the sonic irradiation and proportional in amplitude to the electric current. This process can, in principle, allow determination of the magnitude of a biocurrent in the sound path by detection of the amplitude-modulated component via surface electrodes. This observation has potential application to the noninvasive detection of naturally occurring bioelectric currents in vivo.",
