| Abstract: |
Arrays of vector velocity sensors have exhibited major system improvements over traditional omnidirectional hydrophones in undersea acoustic sensing. Compact accelerometers made from relaxor piezoelectric crystals are the key element which allow for the improved functionality of the vector velocity sensor arrays. These relaxor piezoelectric crystals are extremely sensitive and compact; but manufacturing of sensors incorporating these crystals have traditionally been costly. Mid�'s patented piezo manufacturing line and its over 20 years of experience with manufacturing piezoelectric packages makes them the ideal candidate to develop an effective and low cost manufacturing process for accelerometers incorporating relaxor piezoelectric materials. Mid�'s proposed technology drastically reduces assembly needs for piezo based vector velocity sensors while improving the durability of the piezoelectric element. In the manufacturing process piezoelectric packages are produced with necessary electrical connection to the piezoelectric element embedded. Because of the large number of sensors required, Mid�'s automated piezo production line provides the greatest potential for cost effective manufacturing |
| Benefits: |
Arrays of vector velocity sensors optimize the accuracy with which submarines and unmanned undersea vehicles detect underwater acoustic disturbances. These allow for the detection of quieter targets and the detection of targets at greater distances. Sensors incorporating relaxor piezoelectric accelerometers offer the optimal performance from these sensors but the development of a cost effective manufacturing process is needed. The United States Navy would benefit directly from the proposed research and development from reduced costs and improved performance. The oil exploration industry also requires cost effective, high performing arrays of vector velocity sensors which Mid� will explore in commercialization efforts. HVAC systems and heavy machinery also utilize acoustic sensing/suppression; and these industries can also benefit from the proposed research and development. |
