Cholesterol-Measuring Skin Patches

This Smart Wearable Patch Takes Measurements Through Sweat

This smart wearable patch has been developed by researchers at Caltech as a health technology solution that could expedite the tracking of cholesterol without having to rely entirely on blood work.

The patch, developed by a team led by Profession Wei Gao, works as a physical sensor that leverages a machine learning model that factors in body mass index, gender and sweating. This information is used to create a baseline before accurately estimating blood lipid levels and interpreting data collected by the sensor itself since cholesterol can't be directly measured in sweat.

The smart wearable patch has so far been tested on 24 participants during an early-stage study with additional studies underway to help determine its viability as a healthcare product in the years ahead.
