Nonenzymatic Yarn Sensor for Glucose Monitoring

This paper reports the design, fabrication and characterization of a flexible yarn-based nonenzymatic glucose sensor with three-electrode test configuration. The proposed sensor was implemented with three pieces of functional yarn as working, reference and counter electrode. The WE was a copper oxide and activated carbon-coated copper yarn, the RE and CE were glassy carbon-coated copper yarn. The proposed nonenzymatic glucose sensor achieved a sensitivity of 247.6 μA. mM<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−1</sup>.cm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−2</sup> for glucose concentrations between 0.1 mM and 8 mM.
