A single-axis tilt-mode microelectromechanical accelerometer structure. The structure includes a substrate having a top surface defined by a first end and a second end. Coupled to the substrate is a first asymmetrically-shaped mass suspended above the substrate pivotable about a first pivot point on the substrate between the first end and the second end and a second asymmetrically-shaped mass suspended above the substrate pivotable about a second pivot point on the substrate between the first end and the second end. The structure also includes a first set of electrodes positioned on the substrate and below the first asymmetrically-shaped mass and a second set of electrodes positioned on the substrate and below the second asymmetrically-shaped mass.
