Cover Story: Ferroelectret nanogenerators (FENGs) have gained attention for acoustic applications due to their high electromechanical conversion efficiency and low Young’s modulus. This paper reviews advancements in using FENGs for acoustics. It describes FENG operational mechanisms in acoustics, comparing fabrication methods and materials’ effects on properties. FENG acoustic applications are categorized into sensing, actuation, and energy harvesting. Implementations in these areas are detailed, with future directions and challenges outlined. FENG acoustic applications demonstrate adaptability to diverse needs. By showing FENGs’ wide applications range, this paper exhibits their potential to meet individual acoustic requirements through tailored fabrication and implementation. Further materials and design refinements may yield improved FENG acoustic performance. View this paper
