Detecting diseases early requires the rapid, continuous and convenient monitoring of vital biomarkers. Researchers have now developed a novel sensor that enables the continuous, and real-time detection of solid-state epidermal biomarkers, a new category of health indicators.
Wearable, stretchable sensor for quick, continuous, and non-invasive detection of solid-state skin biomarkers The team's wearable, stretchable, hydrogel-based sensor overcomes the limitations of current methods that rely on biofluid samples, such as blood, urine and sweat. This makes it a promising alternative for wearable, continuous, and real-time health monitoring, facilitating the early detection of conditions such as cardiovascular diseases and stroke.
The team's wearable, stretchable, hydrogel-based sensor overcomes the limitations of current methods that rely on biofluid samples, such as blood, urine and sweat. This makes it a promising alternative for wearable, continuous, and real-time health monitoring, facilitating the early detection of conditions such as cardiovascular diseases and stroke. It can also efficiently monitor athletes' lactate levels, an indication of exhaustion and tissue hypoxia, which affect their performance.
"Our novel hydrogel sensor technology is key to enabling the non-invasive detection of solid-state biomarkers on skin. The ionic conductive hydrogel layer that solvates the biomarkers and the electronically conductive hydrogel layer facilitates electron transport. This bilayer enables the sequential solvation, diffusion and electrochemical reaction of the biomarkers.
The sensor's sensitivity is another advantage, as it can detect solid-state lactate and cholesterol at very low levels. This level of sensitivity approaches that of mass spectrometry, which ensures precise monitoring of these biomarkers. "Another potential application is to use the sensor in the daily monitoring of heart health, as cardiovascular disease accounts for almost one-third of deaths in Singapore. The research team has embarked on a research programme to work closely with cardiologists in establishing clinical correlation between biomarkers -- lactate, cholesterol, and glucose -- with heart health," said Dr Yang.
