Caltech Team Develops Stick-on Patch That Could Reduce the Need for Doctors to Draw Blood for Some Medical Tests

A team at Caltech, led by Wei Gao, developed a stick-on patch capable of gathering lipid measurements by analyzing sweat. These patches measure factors like cholesterol and triglycerides, which are typically required through blood draws for diagnostic tests. This technology aims to reduce the need for doctors to draw blood for certain medical assessments.
