Electrochemical Seismometers of Linear and Angular Motion
Traditionally seismic sensors use a mechanical system with moving solid-state inertial mass in combination with either velocity or displacement transducers. The latter convert mechanical motion of the inertial mass into the electrical signal. An alternative approach based on employment of liquid inertial mass and four-electrode electrochemical transducer with potential difference applied between the electrodes as a converter of the liquid motion into electrical signal was developed in recent years (Huang et al. 2013; Agafonov et al. 2014). Such devices are known as MET (molecular electronic transfer) or electrochemical sensors. Basically, the operation of the MET sensors uses the sensitivity of an interelectrode current in the electrochemical cell to the movement of a liquid electrolyte relative to the electrodes fixed on the sensor housing....
