This work presents an approach to enhance the sensitivity and lower the uncertainty of a tilt sensor based on a dual-axis accelerometer. The arctangent function arctan(a2/a1) instead of traditional arcsine function arcsin(a2/g) or arcsin(a1/g) is used to solve for tilt angle. As a result, the measured sensitivity of tilt angle is kept in the maximum constant value (17.45 mg/°) and the measurement...
This paper reports a micromachined accelerometer using a three degree-of-freedom (3-DoF) weakly coupled resonator (WCR) based on the phenomenon of mode localization. When acceleration acts on the proof masses, the stiffness imbalance between the two outer resonators will incur the mode localization and cause the shift of amplitude ratio. The measured amplitude ratio sensitivity of 7,263,30 ppm/g is...
This paper presents a tilt sensor using two orthogonally arranged micro accelerometers. The arctangent function arctan(a2/a1) instead of the traditional arcsine function arcsin(a2/g) or arcsin(a1/g) is used to solve for the tilt angle. As a result, the tilt angle measurement is kept in the maximum value with a constant sensitivity (17.45 mg per degree) in the full measurement range.
