ABSTRACT:
A stress isolation technique for an accelerometer of the type that has a reed that includes a paddle, a support, and flexures connecting the paddle to an area of the support. The support includes one or more mounting pads through which the reed is mounted. The area of the support adjacent to the flexures is divided into first and second portions, such that the flexures are connected to the first portion and such that the mounting pads are positioned solely on the second portion. The flexures are therefore isolated from stress coupled into the reed through the mounting pads.
