“…In addition to stable operation at high temperatures and pressures, sensor elements for seismic probes should have sufficient sensitivity. One of the interesting solutions could be the use of sensors based on molecular-electronic technology (MET) for such extreme environmental conditions [11,12].…”

The paper considers the development and experimental study of the characteristics of a high-temperature motion parameter sensor based on molecular-electronic technology (MET) operating at elevated pressures. Studies were conducted in an extended temperature range (25–125 °C) with a static external pressure of up to 10 atm. A pilot plant based on a high-pressure chamber with the ability to output an electrical signal was specially designed and commissioned. A family of amplitude-frequency characteristics of a ME sensor in an extended temperature range was obtained for the first time. A theoretical model was constructed and verified to describe the transfer function of the sensor at high temperatures and pressures. The activation energies of active carriers were calculated, and a prediction was made about the possibility of using the developed devices for the needs of the oil and gas mining industries.

Low frequency hydrophone with a frequency range of 1−300 Hz for marine seismic exploration systems has been developed. The operation principle of the hydrophone bases on the molecular electronic transfer that allows high sensitivity and low level self-noise at low frequencies (<10 Hz) to be achieved. The paper presents a stabilization method of the frequency response within the frequency range at a depth up to 30 m. Laboratory and marine tests confirmed the stated characteristics as well as the possibility of using this sensor in bottom marine seismic systems. An experimental sample of the hydrophone successfully passed a comparative marine test at Gelendzhik Bay (Black Sea) with the technical support of Joint-Stock Company (JSC) “Yuzhmorgeologiya”. One of the main results is the possibility of obtaining high-quality information in the field of low frequencies, which was demonstrated in the course of field tests.

“…The sensor is based on an iodide/triiodide (I – /I 3 – ) electrochemical redox couple in gel electrolyte and constructed by simply sandwiching the gel electrolyte with two sets of platinum electrodes. The iodide/triiodide redox couple in aqueous solution has been used for high-performance seismometers and vibration sensors. − Iodide/triiodide in gel electrolytes has been investigated for solid-state or quasi-solid-state dye-sensitized solar cells (DSSCs). , Here we found a novel application of gel iodide/triiodide electrolytes for a single-mode mechanoreceptor with both SA and RA capabilities. The SA and RA responses of the sensor originate from the diffusion and convection of the triiodide ions in the gel electrolyte.…”

This article reports an artificial mechanoreceptor based on an iodide/triiodide (I − /I 3 − ) electrochemical redox couple in poly(vinyl alcohol) (PVA) gel electrolyte. The unique feature of this mechanoreceptor is its capability of rapid-adapting (RA) and slow-adapting (SA) detection with a single sensing modality. The mechanoreceptor is constructed by simply sandwiching the gel electrolyte between two sets of platinum electrodes. The Faradaic current between the anode and cathode contains both RA and SA signals. The mechanoreceptor is also able to differentiate normal and shear displacements. The single-mode detection with SA and RA responses has been successfully demonstrated for both normal and shear inputs. The effects of movement displacement and velocity have been investigated.
