有些动物，如变色龙和头足类动物，具有改变皮肤颜色的非凡能力。这种独特的特性长期以来一直激励着科学家们开发材料和设备来模仿这种功能。然而，它需要拉伸性、颜色变化和触觉传感的复杂集成。在这里，我们展示了一种全溶液处理的变色龙启发的可拉伸电子皮肤（电子皮肤），其中电子皮肤的颜色可以很容易地通过改变施加的压力沿着施加的压力持续时间来控制。因此，电子皮肤的颜色变化也可以反过来用于区分所施加的压力。可拉伸的、高度可调谐的电阻式压力传感器和完全可拉伸的有机电致变色装置的集成使得能够展示具有触摸感测控制的可拉伸电致变色活性电子皮肤。该系统将有广泛的应用，如交互式可穿戴设备，人工假肢和智能机器人。 一些动物和昆虫可以改变皮肤的颜色，但在人造材料中模仿这种功能是复杂的。在这里，作者展示了一种全溶液处理的变色龙启发的可拉伸电子皮肤，能够交互式颜色变化和触觉传感。
Some animals, such as the chameleon and cephalopod, have the remarkable capability to change their skin colour. This unique characteristic has long inspired scientists to develop materials and devices to mimic such a function. However, it requires the complex integration of stretchability, colour-changing and tactile sensing. Here we show an all-solution processed chameleon-inspired stretchable electronic skin (e-skin), in which the e-skin colour can easily be controlled through varying the applied pressure along with the applied pressure duration. As such, the e-skin's colour change can also be in turn utilized to distinguish the pressure applied. The integration of the stretchable, highly tunable resistive pressure sensor and the fully stretchable organic electrochromic device enables the demonstration of a stretchable electrochromically active e-skin with tactile-sensing control. This system will have wide range applications such as interactive wearable devices, artificial prosthetics and smart robots. Some animals and insects can change the colour of their skin, but mimicking such function in man-made materials is complex. Here, the authors demonstrate an all-solution processed chameleon-inspired stretchable e-skin capable of interactive colour changes and tactile sensing.
