英文摘要：

A capacitive biaxial microaccelerometer with a single proof mass is implemented. The sensor is fabricated by silicon-on-glass bulk silicon micromachining successfully, where the ICP etching and the anodic bonding process are utilized. The experimental results indicate the biaxial accelerometer with uniform axial sensitivities, good linearity and high cross-axis sensitivity immunity to the z-axis input. The sensitivity of the x direction is 58.3 mV/gn and y is 55.6 mV/gn ,the linear correlation coefficient of the x direction is 0. 9968 and y is 0. 9961 ,as well as the cross-axis sensitivity of the x direction is 6.17% and y is 7.82%.
