AI-powered spectrometer chip shrinks lab technology to the size of a grain of sand
SMRTR summary
Researchers at UC Davis have built a spectrometer chip the size of a grain of sand that replaces bulky lab equipment with AI and 16 tiny silicon sensors. Instead of physically splitting light, the chip uses a neural network to reconstruct light spectrums at 8 nm resolution. The device fits in just 0.4 square mm and could enable portable medical diagnostics, wearable health monitors, and food safety testing.
