  • Patent number: 11938235
    Abstract: Embodiments of the invention are directed to a self-sanitizing structure that includes a body region having a contact surface that can be contacted by a person during an intended use of the self-sanitizing structure. The self-sanitizing structure further includes an energy source configured to generate electromagnetic radiation and direct the electromagnetic radiation through the body region to the contact surface. The body region is configured to scatter the electromagnetic radiation and pass the scattered electromagnetic radiation to the contact surface in a manner that maintains the scattered electromagnetic radiation that reaches the contact surface as sanitizing electromagnetic radiation. The sanitizing electromagnetic radiation is electromagnetic radiation that is at or above a minimum irradiance level that neutralizes infectious agents.

  • Publication number: 20230225058
    Abstract: Electrical circuitry is produced on the surface of an organic polymer. The electrical circuitry is produced on a support, and a polymerizable composition is brought into contact with the support and the circuitry. The polymerizable composition is polymerized while in contact with support and the circuitry to produce a solid, organic polymer. The electrical circuitry becomes adhered to and partially embedded in a surface of the solid organic polymer. The support may be removed subsequent to the polymerization step to expose the circuitry at the surface of the solid organic polymer.
