Abstract

Abstract: A useful direction to solve the energy problem is the effective repeated use of biomaterial for mechanical energy collection and sensing applications. Here, a feather‐based single‐electrode triboelectric nanogenerator (F‐STENG) by only sputtering copper atoms on the feathers are presented. The feather of F‐STENG, as a natural material, has environmental friendliness, which is different from the polymer materials of other triboelectric nanogenerators. F‐STENG has super durability due to its feather structure self‐healing property. The device has a high output voltage of 90 V and an output current of 3.5 µA. After breaking and self‐healing lots of times, the output performance is also 80% of the original. F‐STENG has a high sensitivity to temperature, humidity, and wind speed, and the sensitivity is 0.50 V °C −1, ‐0.98 V RH −1, and 1.67 μA m −1 s −1 . The output power of F‐STENG is 0.62 mW g −1, which can realize global positioning and photographing to solve the module energy consumption problem. F‐STENG provides an effective way for the application of self‐powered sensors and equipment in military, industrial, transportation, and daily life. Abstract : A single‐electrode triboelectric nanogenerator based on feathers (F‐STENG) is designed. By simple manufacturing process, it is ultra‐light, environmental friendliness, and self‐healing. F‐STENG has a high sensitivity to temperature, humidity, and wind speed, which provides a new way of high‐efficiency energy collection for GPS positioning and photographing. It expands the application scope of self‐powered intelligent devices.
