ROI Calculation Logic

Assuming a 4% reduction in annual fault rates across 1,000 precision devices (from 5% to 1%). With an average repair/replacement cost of $2K (AI est.) per device and $0.5K (AI est.) in annual downtime opportunity cost, the direct and indirect savings are ($2K + $0.5K) × 1,000 devices × 4% = ~$100K/year (AI est.). Including energy loss reduction and product quality improvements, the total economic impact could reach ~$1.0M/year (AI est.).

Speed to Market
4× faster than in-house development
The core technology for condensation detection, including electrode materials, substrate structure, and detection principles, is already established and patented. If a company were to develop an equivalent high-performance detection element from scratch, it could require significant time and cost (estimated ~4.0 years) for material selection, microfabrication, thermal design, and electrical characterization. By licensing this patent, companies can bypass these fundamental technology development phases, focusing directly on integration into existing products or application development, thereby significantly shortening time-to-market to approximately 1.0 year.
