Engineers and neuroscientists at the University of California (UC) San Diego have developed a soft, wearable fingertip patch that continuously tracks a Parkinson’s disease (PD) patient’s levodopa medication levels by measuring chemicals in their sweat, with no batteries required. Tests in healthy volunteers and in Parkinson’s disease patients showed that measurements generated using the device were comparable to those obtained by standard laboratory blood tests.
The wearable device offers a way to continuously track real-time concentrations of levodopa in the body and could enable doctors to precisely customize daily medication schedules for patients at home.
The research was led by Tamoghna Saha, PhD, a postdoctoral researcher in the lab of Joseph Wang, DSc, professor in the Aiiso Yufeng Li Family Department of Chemical and Nano Engineering at the UC San Diego Jacobs School of Engineering. Saha is co-first author of the team’s published paper in PNAS…
