CHEN Gui-hui, LIU Jian-sheng, LI Li, et al. Research on 3D MEMS acceleration sensor for seismic exploration[J]. 2012, 31(4): 70-71+78. DOI: 10.13873/j.1000-97872012.04.038.
a new type of digital geophone equipment used in seismic exploration is one of the developing directions.The structure of a 3D MEMS acceleration sensor
which is different from the traditional three-component MEMS sensor that is composed of three MEMS accelerometers according to the orthogonal angle assembly is described.The overall simulation is carried out by PSpice software.The simulation result shows that the step response and sinusoidal response mostly correspond with the results of the theoretical analysis.
