Wearable skin vapor sensing system for continuous monitoring of various health and lifestyles

This work demonstrates a battery powered wearable monitoring system to measure the volatile organic compounds (VOCs) emanating from human skin. The portable system consists of gas sensors, Wi-Fi and Bluetooth enabled MCU, temperature and humidity sensors on a 33mm x 30mm PCB board. The developed system includes 5 sensors to detect and quantify the VOCs from skin as well as to measure the ambient VOC level. The results show that the developed system is able to distinguish the total VOCs between intermittent fasting and alcohol intake. This wearable sensing system enables detection of VOCs in real-time as well as monitoring of personalized VOC exposures for various lifestyles.

Automated summary

This study introduces a battery-powered wearable monitoring system for measuring VOCs emitted from human skin, capable of distinguishing between different lifestyle-related VOC levels, allowing for real-time monitoring and personalized exposure tracking.
