Recently, skin-attachable wearable electrochemical multi-sensing patches have considerable interests for convenient and accurate real-time monitoring [1]. Moreover, the use of e-textile based on nano materials that are conductive and can detect external stimuli stably is increasing. In this study, we newly developed a nanoporous carbon nanohybrid electrode based on MXene/fluoropolymer for sweat-based multi-sensing patch. The proposed patch is comprised of electrochemical glucose and pH sensors. Through laser carbonization, the fabricated nanohybrid electrode exhibited TiO2 porous fibrous structure that has effective electron transfer, excellent electroconductivity rich in active edges, and is effective for enzyme support. The fabricated glucose sensor showed excellent linearity (R2 = 0.99) and sensitivity (77.12 μAmM-1cm-2) within concentrations of 0.01mM – 2mM, and the pH sensor was able to detect pH values ranging from 3 to 9.
