MEMS are renowned for their ability to record seismic signal with true amplitudes and phases, contrary to geophones whose sensing fidelity varies with manufacturing tolerances, ageing and temperature.
In addition, the third generation of MEMS has overcome the low-frequency limitations associated with previous generations.
A recent field test could demonstrate that contrary to the case with 3C geophones, 3C MEMS have in addition the ability to measure particle motion along truly vertical and horizontal axes, which is a major benefit for OBN applications.
