Abstract

In this Phase I SBIR, Nomadics will build on our past experience with micro-structure resonators and quartz-based sensors to develop a pressure sensor suitable for high pressure applications such as oil and gas industry applications. In the Phase I work, the outstanding measurement resolution of our sensing technology will be demonstrated and the feasibility of this technology for pressure sensing will be demonstrated. Pressure tests with ranges up to 140 MPa will be performed. The pressure sensing range and sensitivity of a commercially available structure will be tested. The material property, behavior, and the mechanical integrity of the chip assembly including the fiber connector under high-pressure environment will be understood. The interaction of pressure fluid in the testing facility and material at various pressures and temperatures will be tested. These efforts will include collaboration with a leader in the oilfield test and measurement industry. Successful completion of the Phase I tasks will warrant continuation into Phase II prototyping.
