SUPPORTING SAFER OCCUPIED ENVIRONMENTS THROUGH INTELLIGENT UV-C SURFACE DISINFECTION
Maintaining cleaner, safer occupied environments remains an ongoing challenge. Microorganisms are continually introduced and redistributed through routine human activity, often by pathways that conventional cleaning practices cannot continuously address.
Footwear is one highly visible and measurable example. Shoe soles routinely contact contaminated surfaces and can transport microorganisms into healthcare facilities, food-processing operations, commercial buildings, transportation hubs, and other occupied environments.
Infinite Shield was initially developed to address this specific pathway. However, its patented Digital Shielding architecture and independently controlled UV-C interface provide the foundation for a broader surface-disinfection technology platform.
WHY FOOTWEAR?
Scientific studies have documented that footwear can carry and redistribute microorganisms throughout occupied facilities. Yet despite its frequent contact with contaminated surfaces and routine movement between spaces, footwear remains largely overlooked and insufficiently addressed within many facility contamination-control programs. Mitigation at entryways and other strategic locations could help reduce this persistent pathway before microorganisms spread farther into a facility.
The consequences of microbial contamination can be substantial. In U.S. acute-care hospitals alone, the CDC estimates that approximately 518,000 healthcare-associated infections occurred in 2023, affecting about one in 38 hospitalized patients on any given day. Beyond the human toll, contamination-related events can generate significant costs through treatment, operational disruption, product loss, recalls, and reputational harm. Footwear is not the sole source of these outcomes, but it represents a persistent and addressable pathway by which microorganisms can enter and spread throughout occupied environments.

WHY INFINITE SHIELD?
Conventional shoe-sole disinfection systems demonstrated that UV-C technology could reduce microorganisms, but they also revealed important limitations in treatment efficiency, effectiveness, and, most significantly, user safety. Infinite Shield was engineered to address these limitations through a compact, modular architecture that precisely controls where and when UV-C energy is delivered. Unlike systems built around a fixed footwear-disinfection configuration, this architecture can also be scaled, reshaped, and adapted to other application geometries. This transforms Infinite Shield from a single-purpose solution into a broader surface-disinfection technology platform.
SAFETY THROUGH PRECISION
Independently controlled treatment cells activate UV-C energy only where treatment is required.
GREATER EFFECTIVENESS
A dense UV-C LED disinfection interface positions the emitters significantly closer to the target surface, increasing available irradiance while reducing treatment time.
MODULAR PLATFORM ARCHITECTURE
The same engineering architecture can support future applications beyond shoe-sole disinfection.
ENGINEERED FOR COMMERCIALIZATION
Practical electronic architecture utilizing readily available board-level components designed to support future prototype development and scalable manufacturing.
INDEPENDENT TESTING VALIDATION
Independent laboratory testing verified rapid pathogen reduction against microorganisms commonly associated with healthcare-associated infections and foodborne illness. The results demonstrate that the engineering architecture translates into measurable disinfection performance. These independently measured results also compare favorably with reported performance data for conventional shoe-sole disinfection technologies, particularly in treatment time and measured pathogen reduction.
