“…The AEI signal can easily be filtered from other signals in living tissue, for example in muscle, as no natural signal has the frequency of an ultrasound wave. Even though acousto-electrical effect has been observed since in the 1940s, 3 it has only recently received interest in the biomedical field. As it is quite recent, relatively little has been written so far about it in this field, nevertheless giving some positive indications about the efficiency of its use in biomedical applications.…”

“…They reviewed the phenomena involved the generation of the AEI signal. 3,4 The changes in conductivity arises from variations in pressure and temperature. Pressure is the primary cause, bringing about adiabatic process of conversion of the mechanical energy of pressure wave to heat, thus changing the temperature.…”

“…Recently, the combination of a sensitivity theorem [8,12,13] and the acousto-electric (AE) effect [14][15][16] first described in [17] has been used to map internal currents [18,19] and dipoles [20]. That is, the relation between the AE voltage signal detected using paired electrodes and the ultrasound (US) pulsed echo signal is used (for instance, the amplitude of the AE signal is proportional to that of the US signal [15], in which the proportional coefficient is about 0.1% MPa À1 in a 0.9% NaCl solution used [16]) for monitoring cardiac [18,20] and nerve [19] activity.…”
