Using non-contact eccentric nanogenerator to collect energy continuously under periodic vibration

Self-powered image array composed of touch-free sensors fabricated with semiconductor nanowires

“…These values are much higher than those determined in previous studies. [54][55][56] The value of Q free-electron for the operating distances of 1, 5, 10, 20, and 30 cm is À2215.1, À271.5, À56.2, À18.4, and À8.3 nC m À2 , which are well consistent with the values of Q Surface . This result indicates that most of the free electrons induced by the Q Surface flow without loss.…”

“…54 Clearly, the charge density of our TFS is much higher than the previously reported values because of the high dielectric constant of the InN NWs. 42,[54][55][56] The higher Q Surface increases the number of free electrons flowing from the ground to the Cu electrode of the TFS, increasing the output current signal. 34 Fig.…”

Spherical Triboelectric Nanogenerator Based on Eccentric Structure for Omnidirectional Low Frequency Water Wave Energy Harvesting

“…The eccentric structure [29] was introduced into the spherical TENG to collect omnidirectional water wave energy and is shown schematically in Figure 1a. The interior of this spherical structure is made up of regular dodecahedron as a substrate, with twelve E-TENGs symmetrically distributed in different directions.…”

Environmentally friendly natural materials for triboelectric nanogenerators: a review

“…14,15 TENGs have the advantages of dexterity, portability, high unit output power, and relatively low manufacturing costs. 16–20 Moreover, TENGs have four operating modes: vertical contact separation, single electrode, sliding, and independent friction electrode modes, 21–25 and have been shown to make great progress in harvesting energy from wind, waves, human activity, water droplets, etc. 26–32…”

“…Her current research mainly focuses on exible functional lms and their energy conversion. and independent friction electrode modes, [21][22][23][24][25] and have been shown to make great progress in harvesting energy from wind, waves, human activity, water droplets, etc. [26][27][28][29][30][31][32] Over the past decade, various studies have been conducted to develop and optimize TENGs, [33][34][35][36][37][38][39][40] showing that their surface morphology, dielectric properties, device structure, and friction layer materials play important roles in determining their performance.…”
