Recently, the vigorous development of flexible piezoelectric nanogenerator and triboelectric nanogenerator (TENG) has attracted more and more attention from researchers. In this paper, we reported a novel double-piezoelectric-layer-enhanced TENG (DP-TENG) to harvest mechanical energy. The DP-TENG can also serve as a self-powered deformation sensor to detect bending motion. To realize the large-scale production and wide application, a sample fabrication method was developed to prepare DP-TENG using low-cost commercial materials, such as PTFE film, Nylon film, and PVDF film. Besides, the DP-TENG can be used to monitor the flow of hot air to serve as a self-powered temperature sensor. This research has provided an effective structural design about piezoelectric-enhanced TENG for harvesting environment mechanical energy, which has bright potentials in the field of self-power deformation system and airflow temperature monitoring.

双压电层增强摩擦电纳米发电机，用于生物机械能的收集和热气流的监测

近年来，柔性压电纳米发电机和摩擦电纳米发电机（TENG）的蓬勃发展引起了越来越多的研究者的关注。在本文中，我们报道了一种新型的双压电层增强型TENG（DP-TENG），用于收集机械能。DP-TENG还可以用作自供电变形传感器以检测弯曲运动。为了实现大规模生产和广泛应用，开发了一种样品制备方法，以使用低成本商业材料（例如PTFE膜，尼龙膜和PVDF膜）制备DP-TENG。此外，DP-TENG可用于监视热空气的流量，用作自供电的温度传感器。这项研究为压电增强的TENG提供了有效的结构设计，以收集环境机械能，
