柔性和可拉伸的微尺度流体装置具有广泛的潜在应用，从用于方便的数字生活方式的电子可穿戴装置到生物医学装置。然而，实现具有动态液体传输的稳定柔性和可拉伸流体微通道的简单方法具有挑战性，因为弹性体微通道的每一种应用都受到其复杂制造工艺和有限材料选择的限制。在这里，显示了用于构建具有异常稳定和拉伸特性的微流体装置的通用策略。该器件表现出优良的上级机械变形能力，包括高应变（967%）和恢复能力，其中应变传感器和压力流量调节装置的应用程序被证明。各种微通道与有机、无机和金属材料组合作为稳定的复合微流体。此外，通过表面化学改性，这些可拉伸微流体装置还可以获得可拉伸性能，以适合广泛的工业和生物医学应用。
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.
