Design of the pH sensing smart dressing. (a) Scheme of the smart dressing for wound healing monitoring, comprising the PEDOT:PSS/IrOx Ps two-terminal sensor printed on a textile substrate and the absorbing gauze. Inset: picture of the textile PEDOT:PSS/IrOx Ps two-terminal sensor (scale bar = 100 μm). (b) Experimental setup used for flow experiments with the smart pad. (c) Real-time, in-flow response of the wearable sensor in U. B. at different pH values; inset: calibration plot (R2 = 0.996). (d) Real-time, in-flow response of the wearable sensor in SWE within the medically relevant pH range; inset: calibration plot (R2 = 0.970). (e) Signal reversibility in SWE; Vapp = −200 mV.
