摘　　要：As sweat biomarker levels are continuously changing over metabolism and daily activities,pathological and physiological processes can be dynamically analyzed by wearable devices.The colorimetric skin-interfaced microfluidic devices that do not have external circuit modules exhibit enhanced deformability with a small footprint.However,it is difficult to achieve sampling over time and self-feedback for closed-loop systems.This review summarizes recent advances in microfluidic valves for biofluid management and chrono-sampling,as well as active triggers in microfluidics self-feedback.After enumerating the current limitations in temporal resolution and reliability,we further point out a few potential feasible strategies for future developments.
