Abstract: An epidermal microfluidic device includes a rigid substrate defining microfluidic features (e.g., portions of channels, valves within channels, and/or portions of reservoirs) with gradient variation in height thereof. A rigid substrate of such a devices may permit flexure during use without breakage and without distortion of microfluidic features therein, such as by providing channel-defining, reduced-width linking portions extending outward between a central portion and reservoir portions, with the reservoir portions lacking direct coupling therebetween. An epidermal interface layer comprising a flexible material and defining a first aperture may be adhered to skin of a user, and multiple microfluidic devices may be sequentially provided over, and removed from, the epidermal interface layer to collect multiple independent, pristine sweat samples during an extended active collection period.
