High performance additional mass enhanced film structure triboelectric nanogenerator for scavenging vibration energy in broadband frequency range

Two Degrees of Freedom in Two Directions Structure Triboelectric Nanogenerator for Vibration Energy Harvesting and Self-Powered Sensing

“…Finally, the length of the rubber band of the vertical TENG was determined to be 30 mm, and the length of the horizontal TENG was determined to be 20 mm. Introducing additional mass on the movable part can improve the electrical output performance of the TENG, 24,33 so the additional mass of the TFTD-TENG was also optimized here. When there is no additional mass, the vertical movable frame is 15 g and the horizontal movable frame is 11 g. Different quantities of copper pieces were selected as the additional masses, where the mass of a single piece is 5 g. Figure 4i shows the output voltage of the TFTD-TENG under different additional masses.…”

“…Qi et al designed a kirigami-inspired TENG (KI-TENG) with two degrees of freedom, using a PET sheet as the elastic element to obtain a wide frequency range output in multiple directions. Yu et al proposed a novel additional mass enhanced film structure TENG (AMF-TENG), and the additional mass is used to increase the mass inertia of the FEP film. When the mass at the center of gravity is relatively light, the output performance is very low under the excitation of mechanical equipment, , and adjusting the parameters of the elastic picking-up vibration structures can improve the response sensitivity under the weak excitation condition. , However, these devices are sensitive to vibration in only a single direction and are generally used to harvest the vertical vibration energy.…”

Highly Integrated Triboelectric‐Electromagnetic Wave Energy Harvester toward Self‐Powered Marine Buoy

“…The triboelectric nanogenerator (TENG), invented by Wang et al in 2012, can effectively harvest mechanical energy from the environment. [15] It has been widely studied for harvesting wind, [16][17][18][19] vibration, [20][21][22] and wave energies. [23][24][25][26][27] Zi et al have systematically compared the output performance of the EMG and the TENG with low-frequency input.…”

Triboelectric Nanogenerator with a Rotational Freestanding Mode for Multi-directional Vibration Energy Harvesting

“…Xu et al put forward a silicone rubber-spring helical structure TENG, which can harvest the vibration energy in both vertical and horizontal directions. However, these devices have the problems of narrow frequency bandwidth and poor flexibility, and the commonly used improvement methods include impacting enhancement nonlinearity, magnetic levitation structure, membrane structure, , or placing a removable mass in the shell. , For example, Vivekananthan et al proposed a hybrid energy harvester made of magnetic particles (MP-HG). Jin et al developed the maglev porous nanogenerator, a triboelectric nanogenerator and an electromagnetic generator that can be realized simultaneously by moving up and down the middle suspension magnet.…”
