Abstract

In this paper we demonstrate a new prototype of a high-precision ultra-low-frequency hydrophone on the basis of a planar type electrochemical transducer (ECT). We have developed a new planar electrochemical microchip and have invented a mechanical system that allows detecting the alternating pressure at low frequencies up to 0.01 Hz. We have obtained the transfer characteristics of our device to convert pressure variation into an electrical signal, and they are very promising. The main advantage of the electrochemical hydrophone is high sensitivity in the infrasound range. The developed sensitive element can become the basis for a new generation of acoustic pressure receivers, vector acoustic receivers, sound pressure gradient loggers.
