Triboelectric nanogenerator by integrating a cam and a movable frame for ambient mechanical energy harvesting

Transform rotary motion triggered by environmental mechanical energy (e.g., wind) to electrical energy is widely used for energy harvesting. Triboelectric nanogenerators that are used to harvest rotational mechanical energy are mostly based on in-plane sliding or free-standing mode. However, the relative friction between the two contacting triboelectric layers may cause severe abrasion, which reduces the durability of the device and increases...
