Xidian University's team, led by Professor Hu Huiyong, just pulled off something massive. They developed a new type of infrared chip — called a SPAD (Single-Photon Avalanche Diode) — using silicon-germanium technology. Simple version? It's a chip that can SEE in the dark. Through fog. Through smoke. Even through some solid materials. 🤯 And they've cut the cost to roughly 1% of what it used to be. We're talking from thousands of dollars per unit… down to about $10. Here's what changes with cheap infrared chips: → 🚗 Self-driving cars can now "see" through dense fog → 📦 Factory robots can scan products through packaging to find defects → 🤖 Humanoid robots stop bumping into things in the dark → 📱 Your smartphone camera could get a massive night vision upgrade Before this? These chips were so expensive they were only used in: 🛰️ Military satellites 🎯 Missile guidance systems 🚁 Drone surveillance Now they're heading to everyday tech. Mass production is expected to begin by the end of 2026, according to Xidian University. This is China's "democratize the tech" moment for infrared sensing. 🌍 Technology has no borders, and neither should our curiosity. 🌟 At AI Tour China, we believe that understanding the global AI landscape requires more than just data—it requires human connection. 🤝 Our Mission: To educate people about AI and robotics. Let's explore, learn, and collaborate for a better and safer future 🌏 #AiTourChina #XidianUniversity #SPAD
