ROI Calculation Logic

Assuming a licensee deploys this technology in 100 healthcare or eldercare facilities. Each facility could reduce annual labor costs for daily disinfection by ~$1,500 (AI est.) by optimizing staff time, and reduce annual electricity costs for conventional powered disinfection devices by ~$500 (AI est.). This totals ~$2,000/facility/year (AI est.). Across 100 facilities, this projects to an annual cost reduction of ~$200,000 (AI est.). Further benefits include potential healthcare cost reductions from lower infection rates.

Speed to Market
6× faster than in-house development
This technology's fundamental research and mechanism validation have been completed by a national research institute, establishing a robust technical foundation.
