Abstract
A vibratory sensor with electronic balancing is provided. The vibratory sensor includes at least one pair of proof masses, at least one tunable spring having electro-thermodynamic characteristics for each first and second proof mass in the at least one pair of proof masses, and a steering circuit. Each pair of proof masses include a first proof mass and a second proof mass. The first proof mass and the second proof mass can move in opposing directions. Each tunable spring couples an associated one of the first and second proof masses to a substrate. The steering circuit is configured to selectively couple current from a power source to each tunable spring to adjust the stiffness of at least one tunable spring to balance relative movement between the first and second proof masses of the at least one pair of proof masses.
