Survey based on type of devices used for seismic data acquisition [31].

Parameters	Molecular Electronic Transducers (MET) Sensor	Geophones	MEMS; accelerometers	Implication
Frequency range	1–500 Hz	10–190 Hz	DC – 1000 Hz	Better imaging of deep, shallow, and/or narrow layers of deposits
Scale factor stability	<50 ng/		500 ng/	Higher data quality
Sensor noise	Low	Low	Moderate	Higher data quality
Sensitivity	High	Low	Low	Longer life in the field
Shock tolerance	Very high	Moderate	High	Usable in a wider range of surveys
Electromagnetic interference	No	Yes	No	No power line pickup: better data with less processing required
Power	Low	Low	High	Less expensive to operate, longer battery life
Cost	Low-med	Low	High	Lower equipment cost
