Endevco Pressure Sensors Designed Into Winning TSA Entry

Endevco Corporation pressure sensors were used in the winning entry at the National Highway Traffic Safety Administration’s Enhanced Safety of Vehicles Conference design competition. A team of graduate students from Wake Forest University’s Center for Injury Biomechanics created the project, titled “Design, Development, and Analysis of a Pulmonary Surrogate for use in ATDs.” The team developed a surrogate lung that provides increased data to improve vehicle safety. Using Endevco’s high-accuracy model 8510C-15 pressure sensors, the model measures pressure spikes in the lungs during vehicle impact testing. This tool can be developed to relate pressure data to injury levels and can provide a predictor for occupant protection of the vehicle being tested. "Since thoracic trauma is second only to head injury rates in automobile accidents, this area of study is extremely important to pursue," Amber Bonivtch, Wake Forest University team member, said in a statement. The Endevco model 8510C is a rugged, miniature, high-sensitivity, high-resonance, piezoresistive pressure transducer that measures dynamic pressure. Available in ranges from 15 psi to 100 psi, some of its features include a four-arm strain gage bridge ion implanted into a unique sculptured silicon diaphragm.
