Abstract: A protective respirator that deactivates pathogens in a kill zone in front of a mouth and nose of a user by emitting Far UV-C radiation (e.g., having a wavelength centered around 222 nanometers). In some embodiments, a controller uses a mathematical model to determine a required intensity or emission time to provide a threshold probability of killing a microbe (e.g., a virus such as SARS-CoV-2). The required intensity or time may be determined based on atmospheric conditions and/or physiological conditions of the user. The Far UV-C radiation may be emitted in a direction through the kill zone that does not intersect with the skin or eyes of the user (e.g., away from the user or across the front of the user's face). Alternatively, the controller may estimate the fluence of Far UV-C radiation at the skin or eyes of the user over time and adjust the Far UV-C radiation emitted.

Abstract: A self-sanitizing surface structure configured to selectively refract light, a method of fabricating a self-sanitizing surface configured to selectively refract light, and a method of decontaminating a surface using selectively refracted light. A waveguide including a support layer below a propagating layer is positioned over a substrate as a self-sanitizing layer. In the absence of a contaminant or residue on the waveguide, UV light injected into the propagating layer is constrained within the propagating layer due to total internal reflection. When a residue is present on the self-sanitizing surface structure, light may be selectively refracted at or near the interface with the residue along the side of the waveguide to destroy the residue. The self-sanitizing surface structure may be configured to refract a suitable amount of UV light in response to a particular type of residue or application.
