Flexible power sources are key power solutions towards wireless wearable electronics, untethered soft robotics, and medical care. However, the high power consumption of various components in modern flexible electronics with limited volume raises great challenges for their sustainable operation. A flexible self-charging system that can harvest energy from the working environment and simultaneously charge energy-storage devices to supply power is a promising strategy. Flexible self-charging devices based on solar cells, triboelectric nanogenerators (TENGs), hydrovoltaics, and other emerging energy harvesting technologies hold the advantages of high power density and lightweight. Therefore, they would meet the critical requirements of next-generation soft electronics. In this presentation, the integration of several energy harvesting and storage devices will be introduced, regarding the materials, designs and applications.<br/>Reference:<br/>1. K. Ni, B. Xu, Z.
