Literature Seminar Abstract

Non-Invasive sensing is a growing global market where the need for continuous, wearable sensors is constantly developing. Specifically, biosensors have been an attractive alternative to bulky and expensive analytical instruments used in health-care today. Having the ability to monitor overall health of a patient without having to draw blood or use other invasive techniques is the ideal system. Recent advances in wearable technologies, directly in sweat sensing, have been able to effectively monitor a person’s overall health. Human sweat contains abundant information about overall health and serves as an excellent biofluid for non-invasive sensing. A group from the University of Cincinnati recently designed a device to effectively wick and detect low volumes of sweat from a subject’s arm with no analyte loss with the film materials. By using open nanofluidic films with a novel hexagonal network design, they are able to do this process in less than three minutes. Their new design addresses significant challenges facing the non-invasive biosensing field but this application can be used to improve the wearable sensing field as a whole.
