ROI Calculation Logic

In thermal power plants and chemical facilities, assuming an average annual downtime of 200 hours due to sudden equipment failure and a production loss of ~$3.5K/hour (AI est.), annual losses could reach ~$1M (AI est.). Implementing this technology could reduce downtime by 50% (100 hours), avoiding ~$0.5M (AI est.) in annual losses. Additionally, if annual personnel and material costs for periodic inspections are ~$1.5M (AI est.), optimizing preventive maintenance could reduce these by 50%, saving ~$1M (AI est.) annually. The total estimated annual cost reduction is ~$1M (AI est.).

Speed to Market
4× faster than in-house development
This technology is a research outcome from a national R&D agency, with its principles already established. Its simple operating principle, detecting electrical resistance changes in metal oxide thin films, allows for easy integration with existing sensing technologies and data processing platforms. Developing a similar heat- and radiation-resistant sensor in-house from scratch could take significant time and cost (approximately 4 years) for material selection, thin-film formation, and reliability evaluation in harsh environments. By licensing this patent, companies could bypass this foundational technology development, potentially enabling prototype implementation and pilot testing within approximately 1 year.
