PROBLEM
Monitoring uric acid (UA) levels in human sweat over long periods of time could enable the unprecedented diagnosis, therapy and prognosis of several conditions including anxiety and hypertension. Current wearable sensors to measure UA levels in sweat have complicated fabrication processes, sophisticated instruments, expensive raw materials and unsatisfactory performance.
SOLUTION
Purdue University researchers have developed EPICS, which are flexible and noninvasive sensors that monitor uric acid in sweat. They are created from zinc oxide, a nontoxic, biocompatible and electrochemically active material.
EPICS have been tested at Purdue University’s Flex Lab since 2021. Results show EPICS outperforms traditional sensors with a demonstrated fourfold enhancement in the UA sensing performance and an exhibited superior sensitivity.
