A molecular-electronic transfer (MET) technology offers an alternative to typical electromechanical devices.
The technology provides high-performance seismic data by means of compact-size rugged easy-to-install instruments.
The operation principles of the MET instruments are based on charge transfer variations due to an electrolyte motion
in a 4-electrode electrochemical cell.
A typical MET transducer cell contains anode and cathode electrodes separated by microporous dielectric spacers.
The cell is filled with a highly concentrated iodine-based electrolytic solution with a small DC-offset voltage applied
between the electrodes.
The physical principles of operation can be shown by an example of an electronic vacuum tube.
If the grid could be made to move in response to an external mechanical acceleration - the Earth's motion, the tube’s current
would be changed accordingly. The signal power would be amplified by many orders of magnitude due to the power source.
In a similar manner, an external acceleration along the sensor input axis causes the MET electrolyte to flow changing
the anode-cathode current. In this system, the electrolyte plays a dual role in the “grid” and the inertial mass.
The resulting power gain eliminates the need for large inertial masses - the liquid electrolyte is just a few grams.
