Flexible polymer-based piezoelectric nanogenerators (PENGs) can convert the suffered pressure force into electrical signals (voltage and current), which can serve as high-performance pressure sensors and energy harvesting devices simultaneously. In recent years, measurable advancements have been made in designing flexible PENGs and more amazing application scenarios have been developed. In this review, we systematically summarized the common-used piezoelectric polymers, various strategies for designing PENGs, as well as different applications in pressure detection and energy harvesting. In addition, the current challenges of polymer-based PENGs were thoroughly discussed.
