Because the reaction also powers the device, the patch requires no battery or external power source.<\/p>\n<p>The research, published in <a href=\"https:\/\/www.pnas.org\/doi\/10.1073\/pnas.2610453123\" target=\"_blank\" rel=\"noopener nofollow\">Proceedings of the National Academy of Sciences<\/a>, demonstrated that the wearable produced measurements comparable with conventional laboratory blood tests while providing continuous monitoring in real time.<\/p>\n<p>Unlike traditional blood sampling, the flexible patch is worn on the fingertip, where sweat glands are particularly dense. A specialised absorbent hydrogel draws sweat from the skin before enzymes convert the presence of levodopa into a measurable electrical signal, allowing the device to function as both sensor and power source.<\/p>\n<p>The work reflects a <a href=\"https:\/\/www.iotinsider.com\/industries\/healthcare\/game-set-monitor-how-glucose-tracking-became-big-medical-iot\/\" rel=\"nofollow noopener\" target=\"_blank\">broader trend in IoT-enabled healthcare<\/a> towards autonomous wearable devices that combine sensing, energy harvesting and wireless connectivity to enable continuous monitoring outside clinical settings.<\/p>\n<p>Researchers tested the patch on healthy volunteers and people with <a href=\"https:\/\/www.electronicspecifier.com\/industries\/medical\/engineering-innovation-brings-hope-for-parkinson-s-cure\/\" rel=\"nofollow noopener\" target=\"_blank\">Parkinson\u2019s disease<\/a>, finding that the wearable accurately tracked changing drug concentrations over time. The study also showed that patients with Parkinson\u2019s cleared levodopa more quickly than healthy participants, helping explain why symptoms can fluctuate rapidly between doses.<\/p>\n<p>The team says the technology could eventually be integrated into a closed-loop therapeutic system in which continuous drug monitoring is linked to an automated drug delivery pump, enabling medication to be adjusted in response to the patient\u2019s needs.<\/p>\n<p>The research was led by Tamoghna Saha, Joseph Wang and Irene Litvan at the<a href=\"https:\/\/www.electronicspecifier.com\/industries\/alternative-energy\/engineers-unveil-passive-cooling-breakthrough-for-data-centres\/\" rel=\"nofollow noopener\" target=\"_blank\"> University of California San Diego<\/a> as part of a long-running collaboration on wearable sensors for Parkinson\u2019s care.<\/p>\n<p>There\u2019s plenty of other\u00a0editorial on our sister site,\u00a0<a href=\"https:\/\/www.electronicspecifier.com\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Electronic Specifier<\/a>!
