“…[3][4][5][6][7] Aerogel can be formed from a large variety of chemicals by replacing the liquid content of a wet gel with air without damaging the gel solid network. 4,5,8,9 Silica aerogels are the rst and most widely studied type of aerogels. [10][11][12][13][14] However, recently the organic polyimide aerogels presented higher potential to achieve enhanced mechanical properties and even exibility over the previously studied aerogels.…”

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.

“…The triboelectric device works on the principle of conjunction of tribo-electri cation and electrostatic induction [1]. The recent reports on active materials for TENGs have mainly focused to enhance the performance by morphology tuning, fabrication methods and selecting the best materials [2][3][4][5][6][7]. The recent reports focused mainly on tribo-active materials like zinc oxide (ZnO), polyvinylidene uoride (PVDF), polyimide aerogel, etc.…”

Triboelectric nanogenerators (TENGs) have marked their applications in various fields, most importantly, in medical devices. The electrical output of the TENGs mainly concentrated on parameters such as electrode separation distance, applied mechanical pressure, surface charge density, and overlapping surface-area. The surface-area of the active layer in TENGs plays a crucial role. Given this, the present contribution is the first report on the utilization of lanthanum oxide (La2O3) as an active material with a large surface-area (~72.33 m2/g) in TENGs. The nanocrystals of La2O3 have been successfully embedded into TENGs architecture through a high-quality screen-printed film with a Teflon-counter surface. The in-house test-rig of TENGs resulted in an output open-circuit voltage of 120 V and a short-circuit current of 23.7 μA. Further, the maximum power density is 7.125 W/m2 at an external load resistance of 30 MΩ. These results suggest that La2O3 is a suitable contender in various self-powered devices.
