Devices, systems, and methods for assessing microbiota of skin are described, including: a skin-covering material including an inner surface and an outer surface, the inner surface substantially conforming to a topography of a skin surface of an individual and including a plurality of signal-generating complexes, one or more of the plurality of signal-generating complexes configured to emit one or more signals in response to at least one type of microbe； an image capture device to capture an image of the inner surface of the skin-covering material, the image including one or more signals emitted from the plurality of signal-generating complexes, and to transform the image into a digital output； and a computing device including circuitry configured to receive the digital output, compare the properties of the imaged one or more signals with a database of reference signal-generating complexes, and generate a digital spatial profile of microbes on the skin-covering material.
