Locations of UV sensor placement on the face covering inside ARMOR (a), coordinate map of UV sensor placement on the face covering (b), and experimental setup using a ZnO-based UV sensor (c). The coordinate map and locations of sensor placement are numbered and color-coded by row, showing the precise locations of the UV sensor during testing relative to both the face covering and the other components of the device. Four components of the experimental setup are shown: the ARMOR prototype connected to a not shown external power supply (1), the Zn–O-based UV sensor (2), electrical wires running from the sensor to a not shown multimeter which recorded electrical resistance (3), and an adjustable tower clamp used to hold the sensor in place while resistance data was measured (4).
