Among these accessories, Butterfly-shaped wing was served as dry electrode for the detection of ECG/electroencephalogram (EEG)/electromyogram (EMG). The right picture shows the manufacture process of bi-HEB patch. Pt-based temperature sensor was sealed with SU-8 photoresist. And all sensors were encapsulated in Nafion-based membrane. c The fabrication processes of pH and glucose sensors. Specifically, PANI-functionalized NPC@MXene/Au electrode was acted as pH sensor. PtNPs-modified NPC@MXene/Au electrode was served as electrocatalysts for glucose detection. d Sweat pH, human temperature, sweat glucose was monitored before and after meals by using bi-HEB patch and commercial sensors.
