Inspired by blood vessel's unique layered and wrinkled morphology for sensing and controlling vascular resistance, here we report a double-layered, highly stretchable, and thermo-/NIR-responsive PNIPAM/clay/MXene hydrogel@thermoplastic elastomer (PCMH@TPE) hybrid microtube with a self-wrinkling surface. The stimuli-induced dynamic wrinkling, excellent elastic recovery, and channel size responsiveness render the microtube with ultrahigh hydraulic pressure sensitivity in response to tensile strain, compression, temperature and remote NIR light, as well as easy flow regulation. We demonstrate that a new elastomer/hydrogel hybrid strategy is opened for smart tubular structures with surface wrinkling that may inspire new research in mimicking the fascinating functions of blood vessels in the monitoring and feedback regulation of everchanging flow pressure.

水凝胶-弹性体混合微管的动态起皱可以实现类似血管的液压感测和流量调节

受血管独特的分层和褶皱形态的启发，用于感知和控制血管阻力，我们在此报告了一种双层，高度可拉伸且具有热/ NIR响应性的PNIPAM /粘土/ MXene水凝胶@热塑性弹性体（PCMH @ TPE）混合微管表面起皱。刺激引起的动态起皱，出色的弹性恢复和通道尺寸响应性，使微管对拉伸应变，压缩，温度和远近红外光以及易于调节的流量具有超高的液压敏感性。
