A non-contact wearable device for monitoring epidermal molecular flux.

ABSTRACT: Existing wearable technologies rely on physical coupling to the body to establish optical^1,2, fluidic^3,4, thermal^5,6 and/or mechanical^7,8 measurement interfaces. Here we present a class of wearable device platforms that instead relies on physical decoupling to define an enclosed chamber immediately adjacent to the skin surface. Streams of vapourized molecular substances that pass out of or into the skin alter the properties of the microclimate defined in this chamber in ways that can be precisely quantified using an integrated collection of wireless sensors. A programmable, bistable valve dynamically controls access to the surrounding environment, thereby creating a transient response that can be quantitatively related to the inward and outward f
