Portable impedance measurement device for sweat based glucose detection

Abstract

The future of disease diagnostics and health care wearables lies in the development of low-cost sensors that can detect minute traces of pathogens or antigens from body fluids. Developments in nanotechnology and biomedical research have already shown us that a nanosensor can be specifically tailored to detect a specific biomolecule. These sensors would allow patients to run point of care diagnostic tests, thereby saving time and cost of running clinical tests and can give early stage disease diagnosis and help physicians to provide personalized treatment. This work involves the development of a configurable electronic sensor platform that will interface with these sensors. The device is tested by quantification of glucose from sweat using a nanosensor developed in the Biomedical Microdevices and Nanotechnology Lab in the University of Texas at Dallas. The platform can be easily configured to run Electrochemical Impedance Spectroscopy based detection test for other biomolecules by using sensor tailored for it.
