“…TENGs have emerged not only as a promising energy conversion technology, but also as a multifunctional platform for developing self-powered sensor systems and wearable electronics. [11][12][13] It works by contact electrification and electrostatic induction mechanism occurring between two different thin films with different electron affinities. 14 Many researchers are continuing their studies to develop new TENG devices collecting various mechanical energies, integrate multiple TENGs into one device, track and develop new materials, or find new usage areas.…”

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.

This paper presents a hybridized triboelectric-electromagnetic generator based on heaving point absorbers to harvest the energy of water waves. The device consists of a cylindrical freestanding grating triboelectric generator (TENG) and a 3-phase tubular electromagnetic generator (EMG). The proposed system incorporates a slider which is capable of moving through a stator under the motion of a floating buoy. The floating component can heave up and down while facing water waves without being affected by the wave direction. The performance of the TENG and EMG units and corresponding electrical outputs are evaluated under various structural, dynamical, and electrical conditions. It isshown that the number of segments in the TENG unit, phase number in the EMG unit, and motion frequency in both harvesters are the key elements in the outputs of the hybridized system. For the first time, the effect of irregular wave motion on the TENG harvester performance is systematically explored using a well-known wave spectrum. Also, the performance of the hybridized system for charging a storage unit is evaluated in details. The presented energy harvester shows a great potential toward harvesting the energy of water waves as well as hydrodynamic sensing applications. In addition, this research provides a framework for the exploration of irregular wave motion in TENG-based energy harvesters.

In this paper, a comprehensive study for a stretchable self-powered pressure sensor is presented to investigate the structural parameters effect on the sensor sensitivity, and the pressure sensor is designed based on a vertical contact-separation mode triboelectric nanogenerator (TENG). By addressing the solid mechanics, electrical, and surface science effects, we discussed the fundamental physics of the TENG pressure sensor. Modeling and simulation by finite element method (FEA) are conducted to clarify the effects of the structural dimensions on the performance of the pressure sensor. In addition, the relationship between the deformation of an interfacial micro-nano structure and the applied pressure on a triboelectric energy harvester (TEH) is analyzed for different microstructures patterns and dimensions. Finally, a comparison is conducted between TENG pressure sensor based on the contact-separation mode (CS) and single electrode mode (SE). The results show that both structure sizes of the pressure sensor and TENG operating modes have a significant influence on the pressure sensitivity of the sensor.
