Images and data corresponding to evaluations of repeatability in epidermal hydration sensors and CMMs. Images of a CMM placed adjacent to a and in contact with c the skin of the forearm. Images of an epidermal hydration sensor partially peeled-off b and attached to d a similar region of skin. e Data from the epidermal hydration sensor and the CMM for a sequential set of ten measurements, each involving application and removal of the device from the skin
