Abstract:
1. A method of making a resonating beam accelerometer (RBA), the method comprising: creating a proof mass from a first quartz material; creating at least two resonators from a second quartz material; and applying a predefined amount of pressure at a predefined temperature for a predefined amount of time to the at least two resonators and the proof mass, thereby forming a direct bond between the proof mass and each of the resonators; creating at least one damping plate from a third quartz material; and applying a predefined amount of pressure at a predefined temperature for a predefined amount of time to the at least one damping plate and the proof mass, thereby forming a direct bond between the proof mass and the at least one damping plate, wherein the third quartz material has a CTE that is within a threshold amount of the first quartz material, 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.
