Abstract
The present work describes a high sensitivity multi-anti-resonance CMOS process compatible MEMS liquid dielectric capacitive tilt sensor. The dual frequency excitation of four electrode structure enables anti-resonance at equally spaced multiple frequencies and capability of measuring the tilt with enhanced sensitivity along with the direction of tilt.
