Claim Text:
1. An accelerometer comprising: a first piezoelectric element having a first polarization, the first piezoelectric element defines an upper surface; a second piezoelectric element having a second polarization, the second piezoelectric element defines a lower surface parallel to the upper surface of the first piezoelectric element, and the first polarization aligned with the second polarization; a first mounting plate that defines a first aperture; the first and second piezoelectric elements extending through the first aperture such that the first mounting plate transects the first and second piezoelectric elements, the piezoelectric elements define a first cantilever portion on a first side of the first mounting plate, and the piezoelectric elements define a second cantilever portion on a second side of the first mounting plate opposite the first side; wherein the first mounting plate defines a periphery comprising: a first arcuate curve portion; a second arcuate curve portion disposed on opposite first arcuate curve portion; a first chord connecting a first end of the first arcuate curve portion with a first end of the second arcuate curve portion; and a second chord connecting a second end of the first arcuate curve portion with a second end of the second arcuate curve portion.
