Abstract  

Electrochemical deposition was effectively used to generate cuprous oxide nanostructure on conductive fabric (CF). Scanning electron microscope, photoluminescence, X-ray photoelectron spectroscopy (XPS), and X-ray diffractometer were used to analyze the samples’ structures and characteristics. As a non-enzymatic glucose sensor, cuprous oxide deposited electrochemically on wearable CF was utilized; CV and DPV were used to examine the sensor’s electrocatalytic reaction to glucose. The results demonstrated that cuprous oxide on CF was synthesized with greater purity, a clean morphological structure, and consistent crystallite size. Having a sword-shaped dendrite, the cuprous oxide-coated CF sensor responds well to glucose. Additionally, it has high stability, a good linear connection between 0 and 500 µM in the concentration of glucose range, a correlation coefficient (R2) value of 0.985, and detection limits of 97.08 µM. Non-enzymatic glucose sensor electrodes have been employed in this study to examine the electrochemical performance of a Cu2O coated on a conductive fabric (CF). Consequently, it has the potential to be used in sensors.
