Embodiments of the invention are directed to a method of forming a self-sanitizing structure. The method includes forming a body region that includes scattering elements in a host composite material. The body region further includes a contact surface that can be contacted by a person during an intended use of the self-sanitizing structure. The method further includes forming an energy source configured to generate electromagnetic radiation and direct the electromagnetic radiation through the body region to the contact surface. Forming the body region further includes configuring the body region to scatter the electromagnetic radiation and pass the scattered electromagnetic radiation through the body region 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.

Self-sanitizing structure for automatically neutralizing infectious agents on the structure's commonly touched surfaces

Embodiments of the invention include a self-sanitizing structure and method of forming the same, where the self-sanitizing structure includes a body having a contact surface that can be contacted by a person, along with an energy source formed as an array of addressable energy sources. The energy source generates electromagnetic radiation and directs the electromagnetic radiation through the body to the contact surface. The body scatters the electromagnetic radiation and passes it through the body to the contact surface in a manner that maintains the scattered electromagnetic radiation that reaches the contact surface as sanitizing electromagnetic radiation at or above a minimum irradiance level that neutralizes infectious agents. A sensor system generates touch data in response to the contact surface being touched, and a controller uses the touch data to control the addressable energy sources.

Self-sanitizing structure for implementing sanitization patterns that neutralize infectious agents on the structure's surfaces

Embodiments of the invention are directed to a self-sanitizing structure that includes a body having a contact surface that can be contacted by a person, along with an energy source formed as an array of addressable energy sources. The energy source generates electromagnetic radiation and direct the electromagnetic radiation through the body to the contact surface. A sensor system is coupled to the contact surface, and a controller is coupled to the energy source and the sensor system. The body scatters the electromagnetic radiation and passes it through the body to the contact surface in a manner that maintains the scattered electromagnetic radiation that reaches the contact surface as sanitizing electromagnetic radiation at or above a minimum irradiance level that neutralizes infectious agents. The sensor system generates touch data in response to the contact surface being touched, and the controller uses the touch data to control the addressable energy sources.
