The electromigration influence on main characteristics of planar electrochemical systems with difference parameters was studied. The transporting processes are simulated, current-voltage characteristic, transfer function and THD were calculated, and quantitative estimates of the magnitude of the asymmetric electromigration flow and its effect on the nonlinearity coefficient of the system are obtained.
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.
Planar electrochemical systems are very perspective to build modern motion and pressure sensors. Planar microelectronic technology is successfully used for electrochemical transducer of motion parameters. These systems are characterized by an exceptionally high sensitivity towards mechanic exposure due to high rate of conversion of the mechanic signal to electric current. In this work, we have developed a mathematical model of this planar electrochemical system, which detects the mechanical signals. We simulate the processes of mass and charge transfer in planar electrochemical transducer and calculated its transfer function with different geometrical parameters of the system.
