Claim:
1. A device comprising: a pendulous proof mass; a support base defining a plane and configured to support the pendulous proof mass; a flexure configured to flexibly connect the pendulous proof mass to the support base, wherein the flexure suspends the pendulous proof mass within the support base, and wherein the pendulous proof mass rotates about the flexure in the plane defined by the support base in response to an acceleration of the device in the plane of the support base; and at least two resonators configured to flexibly connect the pendulous proof mass to the support base and to flex based on the rotation of the pendulous proof mass about the flexure, wherein each of the at least two resonators resonate at a respective resonant frequency, wherein the pendulous proof mass, the support base, the flexure, and the at least two resonators are comprised of a monolithic material, and wherein the pendulous proof mass, the flexure, and the at least two resonators are planar.
