Corona MEMS for Wide Study Area Air Particulate Monitoring

The goal of this project is a low cost device that is able to size and count air particulates with sizes under PM 2.5 and retain the particulates for subsequent composition analysis. Multitudes of such devices can be deployed over a wide study area (such as downtown Sacramento) to monitor the air quality in situ and generate air particulate spatial and temporal maps. We will explore integration with pollutant sensors such as that for NOx and SO2. We aim to extend the applications of a micro corona discharge device to a micro ozone generator for biological sterilizing units, non-mechanical micro air pumps, and ESD control.
