Strategic Study of CAE 2000, Volume 2, Issue 2,   Pages 36-40

Abstract:

In this paper, a newly developed accelerometer based on the principle of area changeable capacitanceand fixed electrodes and CB induced by boundary effect both lower the sensitivity of the accelerometerby about 20 % , and lead to a vertical effect on accelerometer that could be ignored if compared withAfter packaging in IC ceramic die under atmosphere, the accelerometer is put on avibrator to be testedThe experimental results show that the accelerometer has typical sensitivity of 58.1 mV/ (m·s<
