These devices will allow patients to run point of care diagnostics tests, thereby saving time and cost of running clinical tests and ultimately can provide early stage disease diagnosis and enable physicians to provide better-personalized treatment. There have been developments that focus on integrating multiple different tests into a single device that measures analytes from biofluids. Detection of glucose together with some single ions in a single device and test is the current attractive research advancement.Electrochemistry Impedance Spectroscopy (EIS) is widely popular in the medical field where it is used to analyze biological materials as well as characterization of body fluids. It is a complex technique requiring expensive equipment that is also bulky making it difficult to integrate into small form-factor systems that are handheld, wearable and intended for use in point of care testing. This research work focused on developing a proof of concept prototype system with a flexible architecture that can be used for testing multiple sensors using EIS electroanalytical technique. The system is based on an embedded system design to be factored to achieve small valuation time for results along with being compact and portable enough to be used outside laboratory bench setting. The prototype successfully calculates the magnitude and phase of the impedance responses multiple electrochemical cells. The device transmits test data wirelessly to a personal computer or tablet which works together with an analysis and control display. 2018 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1543999395772179 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1543999395772179 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
