Nicotine Detecting Skin-Worn Sensor

Nicotine levels in the air are measured using a skin-worn sensor.

Electronic cigarettes (EC) are thought to be less hazardous than traditional cigarettes but nicotine is one of the most harmful components of e-cigarette vapor. Smoking is the world's leading preventable cause of mortality, accounting for 12% of all adult fatalities. Although tobacco smoking in most nations is gradually dropping, electronic cigarettes (EC) are gaining popularity. A range of mobile health technologies for personal lifestyle and medical aid is available to assist smokers in quitting smoking.

Scientists from the University of Arizona and Royal Melbourne Institute of Technology in Australia have developed a new skin-wearing sensor that can monitor the level of nicotine in the air near the wearer. The prototype batteryless device temporarily sticks to the skin of exposed parts of the user's body, such as the back of their hand.

The skin-worn sensor also includes an NFC (near-field communication) chip, a loop coil for wireless power transmission, and a sensor. As a result, the gadget would be capable of detecting aerosolized nicotine molecules and relaying this information to an NFC-compatible device, such as a smartphone.

This technology can be used to detect the nicotine content in traditional cigarette smoke but requires more sensors.
