The rapid development of portable/wearable electronics proposes new demands for energy storage devices, which are flexibility, smart functions and long-time outdoor operation. Supercapacitors (SCs) show great potential in portable/wearable applications, and the recently developed flexible, smart and self-sustainable supercapacitors greatly meet the above demands. In these supercapacitors, conductive polymers (CPs) are widely applied due to their high flexibility, conductivity, pseudo-capacitance, smart characteristics and moderate preparation conditions. Herein, we'd like to introduce the CP-based flexible, smart and self-sustainable supercapacitors for portable/wearable electronics. This review first summarizes the flexible SCs based on CPs and their composites with carbon materials and metal compounds. The smart supercapacitors, , electrochromic, electrochemical actuated, stretchable, self-healing and stimuli-sensitive ones, are then presented. The self-sustainable SCs which integrate SC units with energy-harvesting units in one compact configuration are also introduced. The last section highlights some current challenges and future perspectives of this thriving field.
便携式/可穿戴电子产品的快速发展对储能设备提出了新的要求，即灵活性、智能功能和长时间户外运行。超级电容器（SCs）在便携式/可穿戴应用中显示出巨大潜力，最近开发的柔性、智能和自维持超级电容器极大地满足了上述要求。在这些超级电容器中，导电聚合物（CPs）因其高柔韧性、导电性、赝电容、智能特性和适中的制备条件而被广泛应用。在此，我们将介绍用于便携式/可穿戴电子产品的基于CP的柔性、智能和自维持超级电容器。本综述首先总结了基于CPs及其与碳材料和金属化合物复合材料的柔性SCs。然后介绍了智能超级电容器，即电致变色、电化学驱动、可拉伸、自修复和刺激敏感的超级电容器。还介绍了将SC单元与能量收集单元集成在一个紧凑配置中的自维持SCs。最后一部分强调了这个蓬勃发展领域当前面临的一些挑战和未来前景。
