Abstract: A three-axis accelerometer includes a single, integrated mass including at least one lateral (x-y) proof mass and at least one vertical (z) proof mass. The vertical proof mass is arranged as a teeter-totter mass, which is located within the lateral proof mass. The vertical proof mass is mechanically coupled to the lateral proof mass with one or more torsional springs, and the lateral proof mass is mechanically coupled to one or more anchors with one or more lateral springs. The at least one vertical proof mass may be symmetrically positioned about one or more axes of the three-axis accelerometer, so that the 3-axis accelerometer has in-plane symmetry. The three-axis accelerometer may be less susceptible for mechanical cross-talk or noise and may provide a smaller packaged solution for sensing acceleration in three directions.
