UC San Diego Develops Battery-Free Wearable Patch to Monitor Parkinson’s Medication in Real Time
Engineers and neuroscientists at the University of California, San Diego have created a soft, flexible fingertip patch that powers itself from sweat and continuously monitors levodopa levels in patients with Parkinson’s disease. The device uses an absorbent gel packed with salts and benign solvents to draw sweat via osmosis; embedded enzymes react with levodopa, generating a measurable voltage that both powers the patch and provides real‑time concentration readouts. Clinical tests with healthy volunteers and Parkinson’s patients showed the patch’s measurements matched the accuracy of standard laboratory blood tests, detecting rapid drug clearance that can lead to under‑dosing or dyskinesia. The researchers published the results in the Proceedings of the National Academy of Sciences and noted the technology could form the basis of a closed‑loop system that automatically adjusts medication dosing.
