E-Nose' Sniffs Out Volatile Organic Compounds

American Chemical Society, June 8, 2022

Researchers from Germany's Karlsruhe Institute of Technology and the University of Pittsburgh developed an “electric nose” (e-nose) that can detect mixtures of specific volatile organic compounds through porous metal-organic framework (MOF) films. The researchers deployed six xylene isomer-adsorptive MOF films in gravimetric sensors, which had different sensitivities to o-xylene, m-xylene, and p-xylene. They used a machine learning algorithm to analyze the sensor array data, and ascertained mixture composition with 86% accuracy for a 10-ppm mixture and 96% accuracy for a 100-ppm mixture. The researchers said the e-nose can be used to discriminate between the three forms of xylene in environmental monitoring and diagnostic health testing. .... '

Body-Monitoring Tech Trend Comes with Concerns

France24, January 6, 2022

Body-monitoring technology promoted at this year's Consumer Electronics Show raises concerns about such wearables eroding the boundary between well-being and obsession. Amaury Kosman at French startup Circular said the company's Circular Ring provides wearers with a daily "energy score" based on activity intensity compiled from heart rate, body temperature, and other sensor-collected data. The ring also tracks sleeping habits, awakes users via vibrations, and syncs with a mobile application to make lifestyle recommendations. German political scientist Nils-Eyk Zimmermann warned such tools could generate a "digital self" that is out of step with reality, adding that society must ascertain whether they are beneficial or "give rise to new dependencies."
