abstract = {The use of facemasks by the general population is recommended worldwide to prevent the
spread of SARS-CoV-2. Despite the evidence in favour of facemasks to reduce community
transmission, there is also agreement on the potential adverse effects of their prolonged
usage, mainly caused by CO2 rebreathing. Herein we report the development of a sensing
platform for gaseous CO2 real-time determination inside FFP2 facemasks. The system con-
sists of an opto-chemical sensor combined with a flexible, battery-less, near-field-enabled tag
with resolution and limit of detection of 103 and 140 ppm respectively, and sensor lifetime of
8 h, which is comparable with recommended FFP2 facemask usage times. We include a
custom smartphone application for wireless powering, data processing, alert management,
results displaying and sharing. Through performance tests during daily activity and exercise
monitoring, we demonstrate its utility for non-invasive, wearable health assessment and its
potential applicability for preclinical research and diagnostics.},
