Figure 3. A face-mask-integrated SARS-CoV-2 wearable diagnostic system. (A) Photographs of the SARS-CoV-2 sensor integrated into a face mask; (B) Breath emission simulator setup; (C) Sensitivity of the A-version face mask sensors at various inputs on the sensor zone of IVT-generated SARS-CoV-2 S-gene RNA; (D) Representative images of lateral flow assay (LFA) outputs from the sensitivity measurements; (E) Specificity demonstration of the sensors shows no cross-reactivity with IVT RNA from other commonly circulating HCoVs; (F) Representative images of LFA outputs from the specificity measurements.
