A Flexible Front-End for Wearable Electrochemical Sensing

This work presents the design and the realization of a flexible front-end circuitry for electrochemical sensing with wearable devices. The hardware combines readout circuitry for amperometric and Open Circuit Potential (OCP) measurements. The sensing platforms are dedicated to lactate and lithium detection in sweat, hence allowing the monitoring of athletes ...

Non-Invasive Monitoring Of Ph And Oxygen Using Miniaturized Electrochemical Sensors In An Animal Model Of Acute Hypoxia

pH and oxygen electrochemical sensors were evaluated in a ventilatory hypoxia rabbit model. The ventilator hypoxia protocol included 3 differential phases: basal (100% FiO2), the hypoxia-acidosis period (10% FiO2) and recovery (100% FiO2). Sensors were tested in blood tissue (ex vivo sensing) and in muscular tissue (in vivo sensing). pH electrochemical and oxygen sensors ...

An Electrochemical Sensor for Determination of Sulfite (SO32-) in Water Based on Molybdenum Disulfide Flakes/Nafion Modified Electrode

The assay for monitoring the content of sulfite ions (SO32-) is essentially important because sulfite has some seriously toxic effects on both environment and human health. For this, a SO32- electrochemical sensor was fabricated utilizing molybdenum disulfide (MoS2) and Nafion. The cyclic voltammetry (CV) and differential pulse voltammetry (DPV) showed that MoS2 had ...
