 Light-Analyzing 'Lab on a Chip' Opens Door to Portable Spectrometers

Oregon State University News, Steve Lundeberg, October 20, 2022

An international team of scientists led by researchers at Finland's Aalto University has developed an artificial intelligence-driven spectrometer from two-dimensional semiconductor materials that fits on a microchip. Oregon State University's Ethan Minot said the accomplishment demonstrates a method for dramatically miniaturizing the light-measuring devices. The researchers said the device is 100% electrically controllable regarding its absorption of optical colors, conferring vast scalability and widespread usability potential. "Integrating it directly into portable devices such as smartphones and drones could advance our daily lives", said Aalto University's Hoon Hahn Yoon. "Imagine that the next generation of our smartphone cameras could be hyperspectral cameras."  ... '
