Evaluation of non-polarized devices. (a) Results of participant-described grading for device-related reactions to e-bandages. For each self-reported, graded reaction, study participants are represented by the following symbols: open circle (HP19), open square (HP4), open right-side-up triangle (HP1), and open upside-down triangle (HP14). (b-c) Representative photographs of participants’ skin before and after device application (b) and device removal (c); photographs are from HP1. (c) “Cleaned” means excess hydrogel was removed to determine if the skin had been discolored; the black circle shows where a protruding Ti wire slightly abraded the skin.
