Abstract: It is shown that due to the presence in the electrokinetic acoustoelectric transducer of both electroosmosis and its inverse electrokinetic phenomenon – the flow potential, the possibility of retransmission of the initial external acoustic field occurs in the transducer when a constant electric field (pumping voltage) is applied in the process of acoustic signal reception. Necessary theoretical substantiation of this phenomenon is given. The data of the full-scale experiment confirming the theory are presented, the detailed scheme of the full-scale experiment is given, and the necessary devices involved in it are listed.

Keywords: electrokinetic phenomena, electrokinetic repeater, electroacoustic and acoustoelectric conversion, electroosmosis, flow potential, energy pumping. and acoustoelectric conversion, electroosmosis, flow potential, energy pumping.
