Sweat contains biomarkers that can monitor various health conditions, from diabetes to genetic disorders. Sweat sampling, unlike blood collection, is preferred by users due to its painless nature.
May 28 2024National Research Council of Science & Technology However, to obtain sufficient nutrients or hormones from sweat for testing, intense physical activity was previously required to induce sweat. This method posed challenges for individuals with limited mobility.
The research team developed a flexible device capable of delivering drugs to sweat glands by applying a current to a hydrogel containing drugs. This device, which is small and soft, can be easily attached to the skin. Sweat induced by the drug is collected in microfluidic channels within the device and analyzed for biomarkers using biosensors.
This newly developed device contributes to the expansion of non-invasive disease monitoring technology based on sweat in healthy adults as well. Furthermore, the technology of delivering drugs through the skin can be utilized not only to induce sweat but also to increase the delivery rate of drugs in localized areas such as skin conditions or wounds, thereby accelerating recovery.
