如何在封面设计中的表现石墨烯light-driven致动器和自供电的传感功能呢？短暂地小组头脑风暴后，在交流过程中突然有人提到了之前看过的电影 《E.T.外星人》  其中封面中的一些元素值得借鉴。

在电影 E.T.外星人 的电影封面中，语言不通的小外星人ET和男主角各伸出一根手指在半空中交汇，通过指尖传感来达到交流的目的。这和研究团队研究结论中的自供电的传感功能有异曲同工之妙......随着越来越多的想法和相关元素在讨论会上涌现，封面设计的雏形也越来越具体。

文章摘要：

Smart actuators integrated with sensing functions are taking a significant role in constructing intelligent robots. However, the detection of sensing signals in most actuators requires external electrical power, lacking in the self-powered feature. Herein, we report a graphene-based light-driven actuator with self-powered sensing function, which is designed by integrating a photo-thermoelectric generator into the actuator intelligently. When one part of the actuator is irradiated by near-infrared light, it shows a deformation with bending curvature up to 1.5 cm−1, owing to the mismatch volume changes between two layers of the actuator. Meanwhile, the temperature difference across the actuator generates a voltage signal due to the photo-thermoelectric effect. The Seebeck coefficient is higher than 40 μV/K. Furthermore, the self-powered voltage signal is consistent with the deformation trend, which can be used to characterize the deformation state of actuator without external electrical power. We further demonstrate a gripper and a bionic hand. Their deformations mimic the motions of human hand (or finger), even making complex gestures. Concurrently, they can output self-powered voltage signals for sensing. We hope this research will pave a new way for self-powered devices, state-of-the-art intelligent robots, and other integrated multi-functional systems.

这一成果近期发表在Nano Research上，并被选为封面文章。

在经过几次细节反复推敲修改之后，封面如上图所示。再次热烈祝贺该团队。

在科学研究中，不同的领域侧重点不同，但在投学术期刊时，封面一般都是少不了的。在没有具体设计想法之前，不妨回忆下之前看过的电影封面,广告设计等，毕竟，灵感总是在不经意间出现。
