KNOWWARE: AUDIO-SPATIAL GUIS FOR BLIND PEOPLE

Not Available MesoSystems Technology (MST) proposes to develop and test a lightweight micromachined aerosol sampler. This will include the fabrication of two devices: (l) MicroVIC with a microcentrifuge: Air-to-air particle concentration in which a small amount of fluid would be added to the concentrated particulates as a final processing step. This collection approach addresses situations where either fluid evaporation or freezing temperatures are a concern and where the biosensors require a liquid sample. (2) MicroRAC: Air-to-water sampler whose biological aerosol samples could be collected directly into water. The product will be a micromachined aerosol sampling system that interfaces with either of these devices, simultaneously collecting, concentrating, and delivering the sample to the appropriate location within the integrated pathogen detection system. The aerosol sampler will be based on the proprietary micromachined aerosol collector technology, currently under development for CBDCOM. The micromachined aerosol collector will identify airborne pathogenic materials for a wide variety of applications including UAV, for individuals, and other civilian uses. We will challenge the collectors with bacterial spores such as Bacillus globigi and a bacteriophage such as MS-2 (virus). BENEFITS: An efficient, lightweight, and small micromachined aerosol collector would easily integrate with biosensors to alert civilian and military, personnel to the presence of pathogens.
