Abstract
A balanced teeter-totter accelerometer has a mass suspended above a substrate, the mass having an axis of rotation that is parallel to the substrate and substantially geometrically centered with respect to the shape of the mass. A physical acceleration in a direction perpendicular to the substrate causes the mass to rotate about the axis of rotation. The rotation is sensed by measuring a change in capacitance of electrodes on the substrate. The accelerometer may be calibrated using the same sensing electrodes.
