In the field of human health, biomarkers are proving a boon that is improving the understanding of the earlier diagnosis of disease.
Biomarkers are helping in the delivery of more effective, safer therapies at much earlier stages. The COVID-19 pandemic demonstrated the need for such a mechanism wherein early detection can help save people's lives.
One such method is human perspiration, which contains ample amounts of physiologically relevant information but has been an underutilized resource for non-invasive health monitoring.
Recent research in the field of wearable sensors has paved the way for many technological advancements related to sweat sensing. Such sensors are now capable of gleaning even minute insights into the dynamics of our bodies.
In this paper, we highlight the potential value of non-invasive sweat-based wearable devices and discuss opportunities to make earlier disease diagnoses, resulting in saved lives.
