外文摘要：In recent years, the increasing demand for the establishment of smart ocean systems has promoted the exploration of self-powered sensing devices. However, a traditional battery has the disadvantages of limited energy storage and frequent replacement. These disadvantages make it difficult to power electronic equipment for a long time, which has become a major obstacle to constructing smart ocean systems. To meet these challenges, a new self-powered sensing device based on a microthermoelectric generator (MTEG) and flag-type triboelectric nanogenerator (FTENG) is proposed. The prototype is a hybrid energy-harvesting system. Through this prototype, solar and wind energy can be harvested simultaneously, and it can be employed to continuously power environmental sensors. In addition, the performance of the prototype was tested. Under the condition of a hot end at 70 degrees C and a wind speed of 10 m/s, the prototype can charge the supercapacitor to 5.5 V in 10 min. Additionally, the prototype can sense and transmit wind speed and direction data. This research provides a new way for the establishment of smart ocean systems.
