Research progress of structure design and application of flexible triboelectric pressure sensor

With the development of artificial intelligence and sustainable energy, the flexible triboelectric pressure sensor has the advantages of lightweight, small size, low energy consumption, stretchability and excellent electrical performance, and has shown strong development potential in the fields of human movement and health monitoring, smart healthcare and human-machine interaction. But up to now, how to obtain high performance of flexible triboelectric pressure sensor through structural design is a key problem. Flexible triboelectric pressure sensors will pay more attention to the design of microstructure and the construction of sensing performance in the future. Therefore, based on the principle of the flexible triboelectric pressure sensor, this paper summarized the core factors that affected the performance of the flexible triboelectric pressure sensor, namely, the selection of core component materials and structural design. At the same time, the working mode of three kinds of flexible triboelectric pressure sensors designed with different structures was introduced, and the influence of different types of structures on their performance was revealed. In addition, the current application fields and existing bottleneck problems of this kind of sensor were summarized. Finally, the future development trend was pointed out. The organic combination of new materials and structural design would be conducive to further promoting the market demand for mass production of flexible triboelectric pressure sensors. © 2024 Chemical Industry Press Co., Ltd..
