Wearable health monitors are everywhere, from Fitbit fitness tracking wristbands to continuous blood glucose monitors for diabetics, but most products have limited information to tell us, and there are problems with accuracy, calibration, and reliability. Swedish researchers are trying to change that.
A technology developed by scientists at kth Royal Institute of technology in Sweden uses multi-purpose electrochemical sensors to measure blood and sweat. These sensors can be woven into clothes, integrated into skin patches or deployed as microneedles, and can be integrated with existing sensors such as accelerometers and ECG sensors to provide important broad-spectrum parameters.
These versatile sensors are different from many current technologies in that they can measure a wide range of important biochemical compounds, such as sodium, chloride, calcium, magnesium, ammonium, glucose, uric acid, and amino acids such as glycine. The sensor can also monitor lactic acid accumulation during strenuous exercise.
Platforms based on this technology can be used in the home medical environment, also can be used in sports activities, they can also be used as diagnostic tools in hospitals and clinics. It can even measure a person's stress and attention, making significant progress in accuracy, ability, analysis and reporting.
