Mechanical energy scavenging using low-dimensional piezoelectric elements has emerged as a promising technique for the energy autonomy of sensors, microsystems and small portable electronic devices. Among these low-dimensional materials, ZnO nanostructures and nanotextured films have become the leading star demonstrating a new pathway for harvesting energy for self-powered wireless nanodevices and nanosystems. Due to its low fabrication cost at the wafer scale and its applicability to a variety of substrates, low-temperature, user- and-environmentally-friendly all-solution based growth of ZnO nanostructures and nanotextured films has been successfully applied for the development of nanogenerators on flexible substrates, including PET, Kapton, wax paper and carton. In this work, we will highlight the advances in flexible nanogenerator technology and the future trends towards efficient mechanical energy haversting.
