A miniaturized sensor for detection of formaldehyde fumes

A novel miniaturized chemical sensor demonstrates high sensitivity for detecting formaldehyde (FA) fumes, with performance comparable to commercial monitoring equipment. The sensor, worn as a bracelet and connected to a smartphone via Bluetooth, converts signal data into a color scale for real-time visualization. It effectively measures FA concentrations across low (20–120 ppb) and higher (1–15 ppm) ranges, making it suitable for environmental monitoring in culturally significant settings like the Summer Palace in Beijing. The study also highlights its potential to assess FA-induced modifications in delicate artifacts, such as a Stradivarius violin, offering a non-invasive tool for conservation research.
