Description
Wenbo Wang and co-authors shrank a carbon dioxide sensor onto a single silicon chip, and report it in 2026. The design uses the non-dispersive infrared method, where gas absorbs a chosen band of infrared light, but builds the light source and the heat-based detector together on one substrate using microsystem fabrication.
Portable uses, from wearables that track breathing to handheld air monitors, need sensors that are tiny and quick, while bench instruments rely on separate bulky chambers. The team co-designed the optical chamber and layout from the physics of light transfer and heat coupling, aiming to catch more of the infrared signal and cut thermal cross-talk. The result targets fast, stable readings in a far smaller package.
