XU Jin-feng, ZHANG Zhi-jie. Research on transverse effect of three axis piezoresistive accelerometer[J]. 2009, 28(3): 33-35. DOI: 10.13873/j.1000-97872009.03.018.
The Hopkinson bar method and free-drop method detected high-range three-axis MEMS sensor’s transverse effect are studied.Considering positive or negative X-axis
Y-axis as the axial shaft
the acceleration size and direction of the sensor’s other two axis are detected.Based on analysis of structural design
there is no transverse effect.But large transverse effect is got in the experiment measurement.Especially considering the z-axis as the horizontal output shaft
obvious horizontal effect is obtained.Considering x-axis or y-axis as the horizontal axis
horizontal sensitivity is relatively small.The results show that certain direction of axial shaft’s output pulse can determin certain direction of horizontal shaft’s output pulse.
