Noninvasive monitoring of markers in biofluids is of paramount significance for health and welfare, which is being integrated into the next-generation consumable wearables. Movement-free sweat extraction and continuous monitoring of fresh sweat are two major challenges for wearable plasmonic sweat sensors. In this perspective, we summary two recent work, in which they integrated an electronic sweat extraction system and a microfluidic system with plasmonic sensors to address the challenge. Future directions in systematic integration and miniaturization are discussed.
