Molecular-electronic technology

The original technology proven since 2004

Unlike traditional seismic sensors, molecular-electronic ones use a liquid inertial mass. A sensitive element inside consists of a system of electrodes attached to the body. These electrodes convert an alternating flow of a working liquid caused by the inertia force into a variation of an electric current between electrodes.

A high ratio of mechanical signal conversion into an electric current and a wide frequency and dynamic ranges have been achieved. These properties, in particular, provide a possibility to produce seismic sensors of a cutoff frequency at low frequencies up to thousandths of a hertz, high sensitivity and low noise level.

A force-balance feedback provides characteristics identical to the level of 0.2%. 

This original technology makes it possible to manufacture seismic instruments based on the physical principles of a molecular-electronic transfer (MET) and a liquid inertial mass.
