Stratio, a Korean deep-tech startup founded by three Stanford Ph.D. graduates, is introducing what it claims is the first germanium-based short-wave infrared sensor designed for large-scale commercial use. During a live pitch session in Pangyo, the company said its “infrared AI” can solve problems that traditional vision AI and standard cameras cannot, including identifying mixed plastics inside recycling facilities, detecting narcotics, and enabling new capabilities inside future smartphones.
