Polarization for 3 of 24 h. (a) Results of participant-described grading of device-related reactions to e-bandages. For each self-reported, graded reaction, study participants are represented by the following symbols: open circle (HP12), open square (HP11), open right-side-up triangle (HP13), and open upside-down triangle (HP20). (b-c) Representative photographs of participants’ skin before and after device application (b), and after device removal (c); photographs are from HP11. (c) “Cleaned” means excess hydrogel was removed to determine if the skin had been discolored.
