Fig. 4: Characterization of stretchable biosensors based on the electrospun SEBS film.
From: A skin-interfaced three-dimensional closed-loop sensing and therapeutic electronic wound bandage
a Schematic illustration of the fabrication process of the stretchable SEBS electrode. b Schematic illustration showing the electrode layout of working electrode (i.e., thermal, pH and glucose sensors), counter electrode (CE) and reference electrode (RE) onto BEWI. c–e Output responses of the glucose, pH and Tem sensors as a function of time. f–h Corresponding calibration curves of the glucose, pH and Tem sensors. i Biocompatibility evaluation of pH, glucose and Tem sensors by live/dead staining. Quantitative analysis of (j) cell viability and (k) cell proliferation co-cultured with different specimens (n = 3 independent replicates, mean value ± SD).
