Description
- Purpose
- The purpose of this project is to improve the performance of a microfabricated optomechanical sensing platform with high intrinsic accuracy based on a fabry-p?ROT microcavity for accelerometer operation and beyond.
- Activities
- The researchers will make several improvements to the optomechanical sensing platform, which has been developed at NIST, to further increase performance. First, they will demonstrate chip-to-chip bonding of the optomechanical cavity to increase dimensional stability and stiffness. Next, they will redesign the accelerometer package to increase its stiffness while reducing its mass. In tandem, the micromechanical resonator within the accelerometer will be redesigned to reduce the amount of mechanical dissipation due to anchor loss and thermoelastic dissipation. These improvements will then be combined to provide a more stable and sensitive accelerometer.
- Expected outcomes
- The researchers? Work is expected to result in optomechanical accelerometers that have higher stability, in terms of sensor signal drift, greater stiffness, which will provide greater accuracy, and higher mechanical quality factor, resulting in higher sensitivity. These outcomes will be used by NIST to perform vibration metrology with unprecedented performance.
- Intended beneficiaries
- NIST will be the primary beneficiary of this research since IT will directly improve our work on vibration metrology. The research will also benefit vibration calibration companies and U.S. Manufacturers of inertial sensors.
- Subrecipient activities
- The recipient does not intend to subaward funds.
