Another week, another wearable. It seems like every week some university shows off its biomedical health trackers off to media outlets. This time is no different, the US National Science Foundation's Nanosystems Engineering Research Center for Advanced Self-Powered Systems of Integrated Sensors and Technologies (ASSIST) that operates out of North Carolina University is showing their Health and Environmental Tracker (HET). The researchers propose a patch-like device that a person would wear on their chest which would enable vital signs to be observed and data to be produced.

The researchers have published their work in the IEEE Journal of Biomedical and Health Informatics under the title: Low Power Wearable Systems for Continuous Monitoring of Environment and Health for Chronic Respiratory Disease. 

"This system will permit a better understanding of the impact of increased ozone levels and other pollutants on chronic asthma conditions," the researchers write in their journal. The device will therefore also assist in measuring how a person who doesn't have asthma can develop asthma due to pollutants in the air. The setup also has a microphone that will listen to the amount of wheezing someone does and will be able to diagnose their conditions more accurately along with the sensors that connect to the head and chest. 

"The data from each sensor is continually streamed to a peripheral data aggregation device and is subsequently transferred to a dedicated server for cloud storage. Future work includes reducing the power consumption of the system-on-chip including radio to reduce the entirety of each described system in the sub-milliwat range," the researchers wrote. 

What we are seeing in the wearables industry is that biomedical research and the monitoring of health is the modus operandi of a lot of researchers right now. Tracking health and technology is something that might save people's lives one days and that is what the engineers are essentially wanting to achieve. 

The Engineering Institute of Technology (EIT) is dedicated to ensuring our students receive a world-class education and gain skills they can immediately implement in the workplace upon graduation. Our staff members uphold our ethos of honesty and integrity, and we stand by our word because it is our bond. Our students are also expected to carry this attitude throughout their time at our institute, and into their careers.
