Abstract

A flexible nickel-phosphorus (NiP) amperometric electrochemical glucose sensor is proposed. A thin layer of NiP was deposited by electroless technique directly onto the Polyethylene Terephthalate (PET) substrate. NiP electroless plating has proved to be a low cost, simple and versatile fabrication technique. Theelectrochemical behavior of the sensor was in agreement with the literature value, with anodic peak at 0.54 Vvs Ag/AgCl. Voltammetric response of glucose was characterized, showing a good sensitivity of the device. Theinfluence of mechanical stress (bending) on the electrochemical response and on the glucose sensing performance of the PET/NiP sensor was examined. Bending the PET/NiP electrode to small radii of curvature (up to 5mm) hasno effect upon the electrochemical behavior, but an increase in sensitivity with respect to flat sensors wasfound.
