Biomimetic skin-like materials, capable of adapting shapes to variable environments and sensing external stimuli, are of great significance in a wide range of applications, including artificial intelligence, soft robotics, and smart wearable devices. However, such highly sophisticated intelligence has been mainly found in natural creatures while rarely realized in artificial materials. Herein, we fabricate a type of biomimetic iontronics to imitate natural skins using supramolecular polyelectrolyte hydrogels. The dynamic viscoelastic networks provide the biomimetic skin with a wide spectrum of mechanical properties, including flexible reconfiguration ability, robust elasticity, extremely large stretchability, autonomous self-healability, and recyclability. Meanwhile, polyelectrolytes' ionic conductivity allows multiple sensory capabilities toward temperature, strain, and stress. This work provides not only insights into dynamic interactions and sensing mechanism of supramolecular iontronics, but may also promote the development of biomimetic skins with sophisticated intelligence similar to natural skins.

超分子仿生皮肤具有广泛的机械性能和多种感官能力。

仿生皮肤状材料能够适应各种环境的形状并感应外部刺激，在包括人工智能，软机器人和智能可穿戴设备在内的广泛应用中具有重要意义。但是，这种高度复杂的情报主要在自然生物中发现，而很少在人造材料中实现。本文中，我们使用超分子聚电解质水凝胶制造了一种仿生离子电子器件，以模仿天然皮肤。动态粘弹性网络为仿生皮肤提供了广泛的机械性能，包括灵活的重构能力，强大的弹性，极大的拉伸性，自主的自我修复性和可回收性。同时，聚电解质 离子电导率允许针对温度，应变和应力的多种感官能力。这项工作不仅为超分子离子电子学的动力学相互作用和传感机制提供了见识，而且还可以促进仿生皮肤的发展，其具有类似于天然皮肤的复杂智能。
