Assessing personal exposure to air pollution has been challenging due to limitations posed by wearable aerosol monitors such as cost, noise, and weight. Enter the ultrasonic personal aerosol sampler (UPAS) developed by Access Sensor Technologies. We have overcome these limitations by creating the UPAS which is a time-integrated filter sampler that utilizes an ultrasonic piezoelectric pump to drive air flow and has a suite of on-board sensors to measure air flow, temperature, pressure, relative humidity, light intensity, and acceleration. All of this data is wirelessly streamed to a phone or computer using the UPAS app. The UPAS increases our ability to understand personal exposure to atmospheric contaminants by reducing the size, weight, and cost of personal air samplers. As a result, both industry and academia have shown great interest in the UPAS system because of how easy it makes workplace sampling, large-scale sampling for epidemiologic studies, and individual sampling for the citizen scientist.
