Ultrasonic Pollution Detector Navy SBIR FY2006.2 Sol No.: Navy SBIR FY2006.2 Topic No.: N06-133 Topic Title: Ultrasonic Pollution Detector Proposal No.: N062-133-0643 Firm: Luna Innovations Incorporated 1703 S Jefferson Street, SW Suite 400 Roanoke, Virginia 24016 Contact: Mark McKenna Phone: (540) 769-8400 Web Site: www.lunainnovations.com Abstract: Luna Innovations will develop a practical compact ultrasonic pollution detection instrument capable of detecting multiple pollutants, paths and monitoring the levels of pollutants such as copper or zinc, for use in environmental monitoring for storm water. Detecting the level of pollutants is an increasing problem as the EPA requires additional monitoring as part of the NPDES permitting process. The device will be based on surface acoustic waves probing affinity layers which can be fabricated for high sensitivity and selectivity to specific chemicals or pollutants. The basis of the device is the small change that occurs in sound velocity in a sensor as the pollutants bind to the polymer layer. This allows a rapid detection which can be sent back to a central monitoring facility. This technology is based on detectors which are used for the detection of biological and chemical hazards. Benefits: Development of such a system can be a low cost, wireless system capable of being deployed in remote locations for detection of pollutants. By using a low cost disposable substrate, the system can be easily upgraded. As this technology is similar to that of the detection of biological and chemical hazards, it can also be used to monitor the water supply system, food or chemical plants. Certainly following any natural disaster such as floods, there is a need to test the water supply for detection of cholera bacteria. Return
