Skin-worn sensor detects and measures nicotine in e-cig vapor

Nicotine is one of the more harmful compounds in the vapor produced by electronic cigarettes, so non-vapers should avoid breathing it in whenever possible. A new skin-worn sensor could help, by monitoring airborne nicotine levels in the wearer’s immedi… Continue reading Skin-worn sensor detects and measures nicotine in e-cig vapor

Wireless sensor grows into bone to monitor health data in real-time

Researchers at the University of Arizona have developed an ultra-thin device that permanently bonds onto bones, and beams data out wirelessly. The breakthrough could allow doctors to monitor the health of a patient’s bones over time, or how well they’r… Continue reading Wireless sensor grows into bone to monitor health data in real-time
