摘要

由于汗液中的生物标志物水平会随着新陈代谢和日常活动而不断变化，因此可穿戴设备可对病理和生理过程进行动态分析。无外部电路模块的皮肤比色微流控设备具有更强的可变形性，且占地面积小。然而，闭环系统很难实现随时间采样和自我反馈。本综述总结了用于生物流体管理和计时采样的微流体阀门以及微流体自反馈主动触发器的最新进展。在列举了目前在时间分辨率和可靠性方面的局限性之后，我们进一步指出了未来发展的一些潜在可行策略。

Skin-interfaced colorimetric microfluidic devices for on-demand sweat analysis

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.
