Thanks to the nanogenerators known as state-of-the-art energy collecting devices, the mechanical energy in every environment can be converted into electrical energy. Some studies on the improvement of the performance of triboelectric and piezoelectric nanogenerators that convert mechanical energy to electrical energy revealed that aerogels brought significant outcomes in the development of nanogenerators. Aerogels, the lightest solid material known, provides a large surface area as the contact area of the nanogenerators, its adjustable porosity allows to improve electronic properties of the nanogenerators, showing its significance in electronics once again. At the same time, the use of aerogels, which is the best candidate in terms of flexibility and mechanical strength required in wearable electronics, in the production of nanogenerators continues to attract the attention of researchers. This study includes an introduction of aerogels and the discussions on the studies involving aerogel based nanogenerators. In the paper, the studies in the literature, focusing on the advantages of aerogel based nanogenerators and their current applications were collected. Three different types of aerogel nanogenerators production were observed to be produced. They are all based on aerogel electrodes produced from different materials, and the paper outlines them with basic working principles. This classification of aerogel nanogenerators and outlining the results will make a significant contribution to the literature and will be a good source for researchers who want to work in this field.
