! Project Summary Exposure to particulate matter (PM) air pollution is the fifth leading cause of premature disease and death on the planet and the number one environmental risk factor for the global burden of disease (posing a greater danger than all other environmental risk factors combined) according to the World Health Organization. Despite the growing need (and demand), the state-of-the-art for assessing personal exposure to PM is based on decades old technology that is inefficient, burdensome, and expensive. The physical burden posed by these monitors (noise, visual aesthetic, and weight) make them difficult to wear. The cost of these monitors also prevents air pollution exposure monitoring at scales relevant to epidemiologic research and occupational hazard surveillance. This Phase II proposal will develop and commercialize a novel, lightweight, and inexpensive personal sampling technology based upon ultrasonic piezoelectric pumping modules. The ultrasonic personal aerosol sampler (UPAS) has the potential to gain a wide share of the air pollution monitoring market. AST proposes developing this sampler into a commercial prototype that is inexpensive (<$200 bill-of-material cost at scale), provides both time-integrated (filter-based) and real-time measurements, is accurate (flow control and PM sampling efficiency within 4% of reference), compact, lightweight (<200g), provides better subject fitment, has no annual maintenance requirements, and virtually silent in operation. Furthermore, the technology will be versatile – able to collect PM2.5 (along with other relevant size fractions such as PM4 and PM10, respirable, and inhalable PM) for sample durations of up to 24 hrs. Taken together, these innovative aspects suggest that the UPAS will be highly competitive with potential for rapid and substantial market penetration. Three aims are proposed: (1) Integrate a novel, real-time PM sensor into the UPAS hardware/firmware; (2) Develop a suite of different plug-and-play size-selective inlets to make the UPAS more versatile and optimize the UPAS for weight, power, performance, and usability; (3) Validate performance of the prototype through laboratory and field testing. !
