The fluid pipes contain various forms of energy, which can be fully utilized to realize the self‐powered pipeline detection. It is a better strategy to convert some negative energy that endangers the operation of pipelines, such as destructive water hammer vibration energy, into electrical energy. Here, it is reported that an Ag interconnects enhanced self‐recovery triboelectric nanogenerator, in which a double‐electrodes energy harvester with self‐recovery polydimethylsiloxane (PDMS) structure is fabricated as the base and the Cu conductive fabric is produced as the electrode. Ag interconnects are added to PDMS substrate to improve the efficiency of charge transfer. The device is able to effectively convert water harmer energy of the fluid in the pipes into electricity. Under a water flow of 12 L min −1 , the peak output voltage and current of the device reached 3.9 V and 0.38 µA, respectively. The amount of charge transferred is 24 nC in 0.2 s. Besides, a single device can be formed into an energy harvesting array to meet the requirements of different environments and performances. This self‐recovery triboelectric nanogenerator provides new strategy and design to harvest energy from fluid pipes to protect them.
