FIBER OPTIC PRESSURE/TEMPERATURE SENSOR

TECHNOLOGY DYNAMICS, INC. (TDI) IS A SMALL R&D COMPANY INVOLVED IN THE DESIGN AND DEVELOPMENT OF FIBER OPTIC SENSORS FOR BIOMEDICAL AND INDUSTRIAL APPLICATIONS. TDI HASDEVELOPED AND IS DEVELOPING DESCRETE FIBER OPTIC SENSORS FORTHE INTRAVASCULAR MEASUREMENT OF TEMPERATURE AND PRESSURE. THE PROPOSED PROGRAM (PHASE I) WILL FOCUS ON ESTABLISHING THE FEASIBILITY OF A SINGLE FIBER, DUAL FUNCTION SENSOR THATMEASURES BOTH TEMPERATURE AND PRESSURE. THIS DUAL FUNCTION SENSOR WILL BE MORE COST EFFECTIVE THAN SEPARATE TEMPERATUREAND PRESSURE SENSORS, AND WILL ALLOW FOR THE DEVELOPMENT OF SMALLER INTRAVASCULAR CATHETERS WITH ATTENDANT INCREASE IN APPLICATION. TDI PROPOSES ESTABLISHING THE FEASIBILITY OF THIS DUAL FUNCTION SENSOR BY: (1) ESTABLISHING REPRESENTATIVE SENSOR REQUIREMENTS AND PERFORMANCE SPECIFICATIONS, (2) REVIEWING APPROPRIATE PATENT AND PROFESSIONAL LITERATURE, (3) DEVELOPING CONCEPTUAL SENSOR DESIGNS, (4) MATHEMATICALLY MODELING AND ANALYZING THE RESPECTIVE SENSOR DESIGNS, (5) IDENTIFYING CANDIDATE SENSOR DIAPHRAGM AND FILTER MATERIALS, (6) PERFORMING FEATURE AND FUNCTIONAL TESTS ON PROPOSED COMPONENTS AND, (7) AS A RESULTOF THESE MODELING AND EXPERIMENTAL EFFORTS, SELECTING A FINAL OPTIMAL SENSOR DESIGN. PHASE II WILL FOCUS ON PROTOTYPE FABRICATION AND TESTING, DESIGN EVALUATION AND IMPROVEMENT, AND FINAL PROTOTYPE FABRICATION AND TESTING.
