An electrochemical transducer (ECT) with the operation principle based in the phenomenon of molecular-electronic transport is a set of electrodes placed into the solution of electrolyte (Fig. 1).As a rule, a solution used contains a high concen tration of background (not participating in the elec trode reactions) electrolyte with a slight additive of the active component for charge transfer through the liq uid/metal interface on the electrode surface. It is known that in this case, it is sufficient to consider only the fluxes of the active component to account only for diffusion and convective transport to calculate the current in the system. The role of the background elec trolyte is limited to screening the electric field in the liquid and thus suppression of migration charge trans port. Operation of the sensor is based on the fact that the rate of the electrochemical reaction on the elec trodes is much higher than the rate of supply of the reacting substances.The principle of ECT operation can be easily explained using the approximation of planar perme able (for liquid but not the charge) electrodes first developed in [1]. When electric voltage is applied to the system, electrochemical current appears (the so called "background current") independent of the presence of mechanical motion (Fig. 2a). In this case, electrochemical reactions cause the development of the concentration gradients of the solution compo nents and charge transport in stationary electrolyte occurs through diffusion of ions from one electrode to another.Abstract-The most important advantage of motion parameter transducers based on mass and charge trans port in electrochemical systems is exceptionally high rate of mechanical signal conversion to electric current. Devices of this class are based on the principle of diffusion charge transport under the conditions of forced convection appearing as a result of external acceleration. This work shows the possibility of development of modern high-technology devices based on an electrochemical transducer developed using up-to-date microelectronic technologies.

Absence of anomalous Nernst effect in spin Seebeck effect of Pt/YIG AIP Advances 6, 015018 (2016); 10.1063/1.4941340Dual resonant structure for energy harvesting from random vibration sources at low frequency AIP Advances 6, 015019 (2016) The results of a comprehensive study of magnetic, magneto-transport and structural properties of nonstoichiometric Mn x Si 1-x (x≈0.51-0.52) films grown by the Pulsed Laser Deposition (PLD) technique onto Al 2 O 3 (0001) single crystal substrates at T = 340 • C are present. A highlight of used PLD method is the non-conventional ("shadow") geometry with Kr as a scattering gas during the sample growth. It is found that the films exhibit high-temperature (HT) ferromagnetism (FM) with the Curie temperature T C ∼ 370 K accompanied by positive sign anomalous Hall effect (AHE); they also reveal the polycrystalline structure with unusual distribution of grains in size and shape. It is established that HT FM order is originated from the bottom interfacial self-organizing nanocrystalline layer. The upper layer adopted columnar structure with the lateral grain size ≥ 50 nm, possesses low temperature (LT) type of FM order with T c
