The characteristics of a frequency-change-type two-axis acceleration sensor must be improved on the point that an undesirable signal from the other axis direction is detected. The signal is caused by the rotation of mass in the sensor. Two methods for improving the characteristics are proposed here and investigated by finite-element analysis. First, the center of gravity in the sensor was moved to realize a linear motion of mass. As a result, the signal became very small from 5.1 to 0.4%, but the volume of the sensor increased by 28%. Next, the other method of adjusting the dimensions of a bent-type support bar was proposed to realize a linear motion of mass. The rotation was not observed when the signal was decreased to almost zero. The method is very useful from the standpoint of realizing the same volume as the sensor of the prototype.
