Gated Metal Oxide Sensors for Human Detection
An essential component of an Advanced Container Security Device (ACSD) system is a low cost, low power, chemical sensor that reliably detects humans hiding in cargo shipping containers. In a Phase I SBIR effort to address this need, Applied Nanotech, Inc., ANI, has developed a solid state sensor to detect changes in oxygen and carbon dioxide levels that occur due to human respiration. ANI has established proof of concept that technology is sufficiently sensitive to enable rapid, accurate, and reliable detection of humans in a closed container. Building on the Phase I technical results, ANI will focus Phase II development efforts on producing a fully qualified, low cost, low power human detection sensor. A significant portion of the Phase II effort will involve application testing of the human detection sensor with strategic development partners that develop or use ACSD technologies. ANI will design and fabricate sensor modules specific to each of its development partner s electrical, mechanical and communications interface requirements. The feedback from field testing will be combined with data from laboratory testing to establish functionality and resilience to harsh environments in which intermodal shipping containers operate.
