Controlled generation of reactive oxygen species (ROS) is essential in biological, chemical, and environmental fields. Here, the authors report that ultrasonication can induce polarization of inert poly(tetrafluoroethylene) to a piezoelectric electret and drive piezocatalytic generation of aqueous ROS.
