Abstract:
1. A method of making a resonating beam accelerometer (RBA), the method comprising: creating a single proof mass from a first quartz material; creating at least two resonators from a second quartz material; placing the single proof mass and the at least two resonators in a tooling device configured to stabilize movement between the single proof mass and the at least two resonators; and applying, via the tooling device, a predefined amount of pressure at a predefined temperature for a predefined amount of time to the at least two resonators and the single proof mass, thereby forming a direct bond by interdiffusing between the single proof mass and each resonator of the at least two resonators, wherein the first quartz material has a coefficient of thermal expansion (CTE) that is within a threshold amount of a CTE of the second quartz material.
