In this study, a low power microcontroller-based NFC interface was designed to function as a battery-less glucose sensor. The abiotic glucose hybrid fuel cell used in this system exhibited good electrochemical behavior and successfully transmitted data to an android application for display.
In this work, a low power microcontroller-based near field communication (NFC) interfaced with a flexible abiotic glucose hybrid fuel cell is designed to function as a battery-less glucose sensor. The abiotic glucose fuel cell is fabricated by depositing colloidal platinum (co-Pt) on the anodic region and silver oxide nanoparticles-multiwalled carbon nanotubes (Ag2O-MWCNTs) composite on the cathodic region. The electrochemical behavior is characterized using cyclic voltammetry and chronoamperometry. This glucose hybrid fuel cell generated an open circuit voltage of 0.46 V, short circuit current density of 0.444 mA/cm(2), and maximum power density of 0.062 mW/cm(2) at 0.26 V in the presence of 7 mM physiologic glucose. Upon device integration of the abiotic glucose hybrid fuel cell with the NFC module, the data from the glucose monitoring system is successfully transmitted to an android application for visualization at the user interface. The cell voltage correlated (r(2) = 0.989) with glucose concentration (up to 19 mM) with a sensitivity of 13.9 mV/mM center dot cm(2).
