Wearable health monitors are everywhere, from fitness tracking wristbands to continuous blood glucose monitors for diabetics, but most products can tell us limited content and have problems with accuracy, calibration and reliability. Researchers are working hard to change this situation.
Scientists have developed a technique that uses multi-purpose electrochemical sensors to measure blood and sweat. These sensors can be woven into clothing, incorporated into skin patches or deployed as microneedles, and can be used with existing sensors such as accelerometers and electrocardiograms. Sensors are integrated to provide important broad spectrum parameters.
These versatile sensors differ from many current technologies in that they are capable of measuring 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 is also capable of monitoring lactic acid accumulation during strenuous exercise.
Platforms based on this technology can be used in the home medical environment or in sports activities, and they can also be diagnostic tools for hospitals and clinics. It can even measure a person's stress and attention, making significant progress in accuracy, competence, analysis and reporting.
Ultrasonic sensors are also becoming more and more medically relevant for health applications and will be an integral part of wearable devices in the future.
