abstract = {For the large amount of waste heat wasted in daily life and industrial production, we propose a new type of flexible thermoelectric generators (F-TEGs) which can be used as a large area bionic skin to achieve energy harvesting of thermal energy. With reference to biological structures such as pinecone, succulent, and feathers, we have designed and fabricated a biomimetic flexible TEG that can be applied in a wide temperature range which has the highest temperature energy harvesting capability currently. The laminated free structure of the bionic F-TEG dramatically increases the efficiency and density of energy harvesting. The F-TEGs (single TEG only 101.2 mg in weight), without an additional heat sink, demonstrates the highest output voltage density of 286.1 mV/cm2 and the maximum power density is 66.5 mW/m2 at a temperature difference of nearly 1000 °C. The flexible characteristics of F-TEGs make it possible to collect the diffused thermal energy by flexible attachment to the outer walls of high-temperature pipes and vessels of different diameters and shapes. This work shows a new design and application concept for flexible thermal energy collectors, which fills the gap of flexible energy harvesting in high-temperature environment.}
