PIEZOELECTRIC ACCELEROMETER

摘要

At least some of the example embodiments are methods including measuring motion of a body by deflecting a first cantilever portion of a sensing element, and deflecting a second cantilever portion of a sensing element, the second cantilever element of the sensing element disposed opposite the first cantilever element. A first voltage having a first polarity is created across electrical leads responsive to the deflecting of the cantilever portions opposite the direction of the first acceleration of the body. The sensing element is supported by way of a mounting plate medially disposed on the sensing element.

1. A method comprising:
measuring motion of a body by
deflecting a first cantilever portion of a sensing element, the deflecting along a direction opposite a direction of a first acceleration of a body;deflecting a second cantilever portion of a sensing element, the deflecting along a direction opposite the direction of first acceleration of the body, the second cantilever element of the sensing element disposed opposite the first cantilever element;creating a first voltage having a first polarity, the first voltage created across electrical leads responsive to the deflecting of the cantilever portions opposite the direction of the first acceleration of the body;wherein the sensing element is supported by way of a mounting plate medially disposed on said sensing element, the mounting plate defining 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; anda second chord connecting a second end of the first arcuate curve portion with a second end of the second arcuate curve portion.
