The disclosed invention provides a sweat sensing device configured with self-aligned sweat stimulation means to provide adequate sweat generation for continuous monitoring of sweat. The disclosed device includes one or more analyte-specific sweat sensors that self-align with sweat glands. In one embodiment, the sweat sensing device includes means to protect the self-aligning sensors from abrasion against the skin or device components. In another embodiment, the device includes prolonged sweat stimulation for the self-aligning sensors through diffusion of a sweat stimulating compound into the skin.
