    Abstract: An accelerometer comprising a measuring mass (1405) for detecting acceleration, including a housing having a cavity, one or more spring mass assemblies (1400) positioned within the cavity, wherein each spring mass assembly (1400) includes a support structure (1410), including one or more resilient folded beams (1415a-1415d) coupled to the support structure (1410) and the measuring mass (1405) is coupled to the resilient folded beams (1415a-1415d), wherein one or more electrode patterns are coupled to the spring mass assembly (1400), wherein a top cap wafer, including a top capacitor electrode, is coupled to the measurement mass (1405), and a bottom cap wafer, including a bottom capacitor electrode, is also coupled to measurement mass (1405). The folded beams include circular cutouts so as to provide stress relief at connections between foot and leg positions of each folded beam.
