Towards wearable skin sensors for biomonitoring and drug delivery

Wearable health devices such as contact lenses and mouth guards could allow patients to monitor biomarkers for their health in real-time providing vital information on the progression of their disease. Huanyu Cheng of Penn State University Department of Engineering Science and Mechanics (PA, USA) has published numerous research articles on the topic of wearable technology for biomarker real-time monitoring and drug delivery. A comprehensive review article published by Cheng in the journal Microsystems and Nanoengineering focused on noninvasive devices, which sample biomarkers from saliva and tears and selective delivery of medication to the affected areas. The devices function by adhering...
