Sensitivity Adjustment of a Five-Electrode Electrochemical Seismic Sensor

Modern electrochemical seismic sensors operate over a wide frequency range due to molecular-electronic transfer (MET) technology. One of the main advantages of this type of sensor is the ability to control sensitivity. Previously, four-electrode and six-electrode cells have been studied. In this paper, we investigate the features of a five-electrode sensor and a method to control its sensitivity. The results showed that we are able to change the sensitivity by more than ten times, which is five times better than that of a six-electrode sensor
