Simple sweat sensors could replace some blood tests

Embargoed until: Publicly released:

We might be able to do away with blood tests for some conditions and instead use a non-invasive alternative based on our sweat. UK researchers reviewing the latest advancements in wearable sensing technology say we can now measure components in sweat and correlate them to particular health conditions such as diabetes and cystic fibrosis. They say new wearable sweat sensing devices can provide continuous health monitoring tailored to individuals without the need for lab tests or hospital visits.

Wearable Flexible Sweat Sensors for Health Care Monitoring: a Review

Going to the doctor’s for a blood test can be a dreaded experience for many people. The good news is that a non-invasive alternative to check for diseases may be on the horizon, using our sweat as the source of physiological information. With recent advancements in wearable sensing technology, components in sweat can now be measured and correlated to health conditions such as diabetes and cystic fibrosis. With sophisticated integrated sweat collection methods, on-site circuitry, and signal processing, wearable sweat sensing devices have shown potential to provide highly individualized continuous health monitoring without the need for laboratory testing or hospital visits.
