Sensors made from ‘frozen smoke’ can detect toxic formaldehyde in homes and offices

Researchers have developed a sensor made from ‘frozen smoke’ that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far beyond the sensitivity of most indoor air quality sensors. The researchers, from the University of Cambridge, developed sensors made from highly porous materials known as … Read more
