A Illustration of the induction of cortisol secretion by an acute physical stimulus synthesis of the MIP layer for cortisol sensing. B Surface structure of the three-electrode carbon electrode, C deposition of CNT on the printed electrode surface with increased surface attachment duty cycle, D electrochemical deposition of PB, cortisol, and Py on the printed carbon electrode. E The trapped cortisol template is eluted from the polymerized PPy, and the corresponding MIP recognition layer after cortisol elution, in which a cortisol-specific cavity is formed in the electrode; Touch-based palm-based sweat cortisol acquisition sensor, and F the sensor mainly consists of a three-electrode system, SE printed on SEBS substrate, and FPCB. G Illustration of the sensing mechanism in which cortisol diffused from accumulated palm sweat through the hydrogel to the MIP electrode. H Schematic diagram of the chemical structure and chemical formula of MIP.
