Wearable patch detects glucose levels, body temp in human sweat

New York: A team of researchers has created a novel wearable patch that can detect specific glucose levels in human sweat for three weeks while simultaneously monitoring body temperature and pH levels.

Continuous monitoring of sweat can reveal valuable information about human health such as the body's glucose levels.

The researchers from Penn State University in the US have now created a new wearable sensor with a laser-modified graphene nanocomposite material.

"Sweat is ideal for real-time, continuous and non-invasive biomarker detection. But low biomarker concentration levels in sweat and variability of other factors such as pH, salinity and temperature have pushed previous sweat biosensors past the limits of their detection and accuracy," said principal investigator Huanyu "Larry" Cheng.
