Abstract
We were interested in experimentally evaluating the sensitivity and laboratory performances of a second generation design of a new sub-epidermal moisture (SEM) measurement device (SEM-2) that is able to identify localised fluid content changes in skin and subdermally, which may precede a pressure ulcer (PU)/ injury (Provizio SEM Scanner, Bruin Biometrics LLC, Los Angeles, CA).
Two laboratory phantoms, of the heel and facial cheek/chin tissues, which were described in our published work, were used here for a systematic comparison of the SEM-2 with the first-generation device (SEM-1) which was used in reported large clinical studies, that is, the SEM Scanner (model 200 of the aforementioned manufacturer).
