A fundamentally new working principle into the field of self‐powered heavy‐metal‐ion detection and removal using the triboelectrification effect is introduced. The as‐developed tribo‐nanosensors can selectively detect common heavy metal ions. The water‐driven triboelectric nanogenerator is taken as a sustainable power source for heavy‐metal‐ion removal by recycling the kinetic energy from flowing wastewater.
