Flexible and stretchable microscale fluidic devices have a broad range of potential applications, ranging from electronic wearable devices for convenient digital lifestyle to biomedical devices. However, simple ways to achieve stable flexible and stretchable fluidic microchannels with dynamic liquid transport have been challenging because every application for elastomeric microchannels is restricted by their complex fabrication process and limited material selection. Here, a universal strategy for building microfluidic devices that possess exceptionally stable and stretching properties is shown. The devices exhibit superior mechanical deformability, including high strain (967%) and recovery ability, where applications as both strain sensor and pressure‐flow regulating device are demonstrated. Various microchannels are combined with organic, inorganic, and metallic materials as stable composite microfluidics. Furthermore, with surface chemical modification these stretchable microfluidic devices can also obtain antifouling property to suit for a broad range of industrial and biomedical applications.

生物启发的基于通用弹性体的微通道

柔性和可拉伸的微型流体设备具有广泛的潜在应用，从方便数字生活方式的电子可穿戴设备到生物医学设备。然而，由于弹性体微通道的每一种应用都受到其复杂的制造过程和有限的材料选择的限制，因此通过动态液体传输来实现稳定的柔性和可拉伸的流体微通道的简单方法一直是具有挑战性的。在此，显示了一种构建具有异常稳定和拉伸特性的微流体装置的通用策略。这些设备具有出色的机械变形能力，包括高应变（967％）和恢复能力，并在应变传感器和压力流量调节设备中得到了证明。各种微通道与有机，无机和金属材料作为稳定的复合微流体。此外，通过表面化学改性，这些可拉伸的微流体装置还可以获得防污性能，以适合广泛的工业和生物医学应用。
