An individual’s exposure to airborne pollutants can vary significantly with time of day and geographic location as a person moves about their daily lives. Thus\, to accurately assess th e health impacts of personal exposure\, new sensory techniques are needed to enable real-time monitoring with high spatial and temporal resolution. The most significant factor in air quality is exposure to aerosolized part iculate matter (PM). Traditional PM monitoring relies on bulky and expensi ve instruments\, such as mass spectrometers\, or techniques requiring high power consumption or complex analysis procedures\, such as incandescence and fluorescence\, none of which are readily amenable to real-time operati on in a portable/wearable monitoring platform capable of achieving high sp atiotemporal resolution. To overcome the limitations of existing technolog ies\, our team has introduced a microfluidic platform that utilizes the in ertial capture of atmospheric PM into a liquid sample\, enabling downstrea m detection and chemical composition analysis of PM using electrochemical methods within a flow cell. Our microfluidics approach enables miniaturiza tion\, increased sensitivity\, and the integration of multiple CMOS-compat ible analysis techniques to facilitate personal PM exposure monitoring. Th is presentation will address various challenges in developing a fully func tional personal PM monitoring system\, from the design of specialized elec trochemical instrumentation to modern microfluidic fabrication techniques using 3D printing to enhance performance. Topics of focus will include a p otentiostat circuit that expands the electrochemical potential window for modern CMOS processes with power supplies below 3V and an analysis of micr ofluidic fabrication options and their respective challenges when utilized to capture aerosol samples and analyze them electrochemically within an i ntegrated platform.\n\nSpeaker(s): Derek Goderis\, Andrew Mason\n\nRoom: 5 08\, Bldg: Roberts Building\, 508\, University College London\, London \, England\, United Kingdom\, WC1E 7JE\, Virtual: https://events.vtools.ieee. org/m/427876 LOCATION:Room: 508\, Bldg: Roberts Building\, 508\, University College Lond on\, London \, England\, United Kingdom\, WC1E 7JE\, Virtual: https://even ts.vtools.ieee.org/m/427876 ORGANIZER:a.demosthenous@ucl.ac.uk SEQUENCE:25 SUMMARY:CAS Webinar: Developments in Real-Time Wearable Airborne Particulat e Matter Detection and Analysis URL;VALUE=URI:https://events.vtools.ieee.org/m/427876 X-ALT-DESC:Description: <br /><p class="MsoNormal" style="text-align: justi fy\;"><span lang="EN-US">Exposure to air pollution consistently ranks amon g the leading global causes of illness and death\, and the World Health Or ganization estimates that nearly 99% of the global population live in envi ronments that do not meet air quality standards.
