From: Fabric-based lamina emergent MXene-based electrode for electrophysiological monitoring
a Photograph image of spray-coated MX-CNF-PCE of FLEXER. b SEM and EDX elemental mapping of MX-CNF-PCE. c Comparison of the sheet resistances of the MXene-based electrodes: pristine MXene, MX-CNF, and MX-CNF-PCE. Bar chart showing sample means (n = 8) with standard deviation error bars. d Skin impedance comparison between the reference dry and wet Ag/AgCl electrodes and pneumatically fully activated FLEXER. Normalized resistance stability measurement under four different conditions: e tensile strain showing sample means (n = 5) with standard deviation error bars, f 1000 cycles of 15% bending strain test, g 100% humidity environment showing sample means (n = 5) with standard deviation error bars, and h an artificial sweat droplet showing sample means (n = 5) with standard deviation error bars. i XRD measurement. j XPS graph. k XPS analysis results of Ti2+/Ti3+ area ratio and hydrogen bond ratio comparison referring from XPS deconvoluted peaks’ area.
