Electrochemical Wearable Devices

Abstract

With the rapid emergence of mobile devices and telemedicine, electrochemical wearable devices capable of detecting and monitoring specific biomarkers in a noninvasively and timely manner have attracted huge attention across various applications. They offer distinctive possibilities for a personalized healthcare monitoring system by detecting and keeping track of target molecules in different biofluids with high specificity and sensitivity via versatile sensing platforms. This entry in the Encyclopedia of Electrochemistry reviews recent advances and developments of the electrochemical wearable device and provides a survey of basic sensing principles and target sampling methodologies. Major and minor obstacles that still exist in the commercialization of this sensing platform will also be covered at the end of this article. With continued tactical innovation and attention to critical challenges, such electrochemical wearable devices are expected to pave the way for the realization of distributed on‐body sensors in a variety of application areas.

“…To detect glucose, [112][113] typically catalyzed by glucose oxidase (GOx or GOD), this process generates hydrogen peroxide as a product, which is subsequently oxidized on the working electrode. This oxidation process generates electrons on the electrode surface, and the resulting current is directly proportional to the amount of glucose present.…”
