Scientists from NTU Singapore have made a groundbreaking development in health monitoring with the creation of a plaster-like microlaser device that accurately measures glucose levels in sweat. This innovative ‘band-aid’ can detect body biomarkers, such as glucose, lactate, and urea, which are indicators of various health conditions.

Unlike traditional methods that require invasive procedures like finger prick tests for diabetic patients to monitor blood glucose levels, this new device offers a non-invasive and painless way for individuals to track their health on a daily basis. By encapsulating a microlaser in liquid crystal droplets and embedding it within a soft hydrogel film, the NTU team has produced a compact and flexible light-based sensing device that provides precise biomarker readings within minutes.

This technology eliminates the need for expensive and rigid sensor-based monitoring devices that must be attached to the skin for extended periods. The plaster-like microlaser device offers a convenient and effective solution for patients to monitor their health status without the discomfort associated with traditional monitoring methods.

The development of this innovative device represents a significant advancement in the field of health monitoring and has the potential to revolutionize the way individuals manage their health. With the ability to accurately measure key biomarkers through sweat analysis, this technology opens up new possibilities for non-invasive health monitoring that is accessible and user-friendly.
