spectrometer chip shrinks lab technology to the size of a grain of sand Scientists built a grain-of-sand-sized AI chip that could turn future gadgets into powerful chemical and medical scanners. Date: May 26, 2026 Source: SPIE--International Society for Optics and Photonics Summary: A new AI-powered chip from UC Davis can analyze light and chemicals using a device tiny enough to fit almost anywhere. By combining smart silicon sensors with machine learning, it achieves lab-style spectral analysis without the bulky equipment.Seems nice :-)
