有这样一款神奇的皮肤贴，可拉伸，可弯曲，可以贴在你身上的任何部位，然而他并不是膏药，今天要说的东西，比膏药不知高到哪里去了！
好了回归正题，下图就是这款皮肤贴，虽然看着其貌不扬，但是它的功能却高端很多，比如随时监测你的心跳。
这是韩国KAIST Institute for the Nanocentury 的Seokwoo Jeon 研究团队的最新发明。皮肤贴虽然粘得牢，却不需要使用任何粘结剂，因为它的粘结原理是模仿壁虎足底的微纤毛。通过合理优化的微观凸起几何结构，这个皮贴可以牢牢地贴在皮肤表面，并可重复使用。
（皮贴表面的微观形貌，AR3与AR4代表两种具有不同几何参数的微观凸起结构。并且经多次使用后，微观结构破坏程度较小，仍能维持较强的粘力。）
通过在PDMS基质中掺杂碳纳米管与石墨烯，皮肤贴自身可以导电。研究者将其简称为导电干胶。因此，这种皮贴可以方便地构成一些电器件的有效部件，研究者将其与检测元件相连，构成脉搏检测器。
除此之外，含有的微观结构使得皮肤贴具有超疏水的性质。其粘结机理也决定了即使在水环境下，它也有着不错的粘力。

总体而言，粘结材料虽然历史很长，但是其功能的开发与创新还是非常活跃。除了以上的例子，人们还希望粘结材料可以更加生物友好、结构更简化，并赋予其更多的功能。希望该领域前沿科技能持续地带给我们惊喜！

Here we propose a concept of conductive dry adhesives (CDA) combining a gecko-inspired hierarchical structure and an elastomeric carbon nanocomposite. To complement the poor electrical percolation of 1D carbon nanotube (CNT) networks in an elastomeric matrix at a low filler content (∼1 wt %), a higher dimensional carbon material (i.e., carbon black, nanographite, and graphene nanopowder) is added into the mixture as an aid filler. The co-doped graphene and CNT in the composite show the lowest volume resistance (∼100 ohm·cm) at an optimized filler ratio (1:9, total filler content: 1 wt %) through a synergetic effect in electrical percolation. With an optimized conductive elastomer, gecko-inspired high-aspect-ratio (>3) microstructures over a large area (∼4 in.2) are successfully replicated from intaglio-patterned molds without collapse. The resultant CDA pad shows a high normal adhesion force (∼1.3 N/cm2) even on rough human skin and an excellent cycling property for repeatable use over 30 times without degradation of adhesion force, which cannot be achieved by commercial wet adhesives. The body-attachable CDA can be used as a metal-free, all-in-one component for measuring biosignals under daily activity conditions (i.e., underwater, movements) because of its superior conformality and water-repellent characteristic.
