of energy collection. [1][2][3][4][5] However, ambient mechanical energy is characterized as having a wide range of operating frequencies, low amplitudes, randomness, and irregularity. [6][7][8] This sets a barrier for the mechanical energy collection for electromagnetic generators with weak performance in power generation at low frequencies. [9,10] In 2012, triboelectric nanogenerators (TENGs) with high power density, high energy conversion efficiency, and low costs were proposed by Wang's group, [11] which aroused comprehensive attention on the aspect of energy harvesting research. [12][13][14][15][16][17] Based on the coupling of triboelectrification effect and electrostatic induction, TENGs show excellent characteristics at low frequency and low amplitude, so they can convert ambient mechanical energy into electrical energy efficiently. [18][19][20][21][22][23][24] Researchers have investigated harvesting energy from the ocean, human motion, and vibration and wind in the environment. [25][26][27][28] Depending on its operating principle, the output characteristics of TENGs, especially the current, are determined by the external excitation. [29][30][31][32] However, the randomness and irregularity of energy from the environment results in an output performance of TENGs that is usually irregular and uncontrollable. [33,34] This has become one of the key problems restricting their applications.In the paper, the research philosophy of a mechanical regulation triboelectric nanogenerator (MR-TENG) with controllable output performance for harvesting random energy is proposed for the first time. Through the combination of the energy storage structure and the control switch structure, the controllable output of TENG under random excitation is achieved. The MR-TENG is made up of five main components: transmission unit, switch structure, generator unit which includes stator and rotor, flywheel, and shell. The structural transmission unit transfers random linear or rocking motions in the environment to the flywheel. The rotor of the generator unit fixed on the flywheel includes six flexible blades and a thin-walled cylinder. The stator of the generator unit includes a shell with 12 copper electrodes pasted equidistant on the inner wall of this shell. The rotor and stator cooperate to convert rotational kinetic Recycling of random mechanical energy in the environment has become an important research hotspot. The triboelectric nanogenerators (TENGs) were invented to harvest energy, and have been widely applied due to their simple structure, small size, and low cost. This paper reports a mechanical regulation triboelectric nanogenerator (MR-TENG) for the first time with controllable output performance used to harvest random or irregular energy in the environment. It comprises a transmission unit, switch structure, generator unit, flywheel, and shell. Random linear motion or rocking motion is transferred via the transmission unit to the flywheel. The rotor of the generator unit fixed on the flywheel and the stator of the gen...

With the diminution of energy sources and the need for using cleaner energy, alternatives must be found. In addition, the desire to supply energy to autonomous low‐power electronics has spurred interest in triboelectric materials. An arch‐shaped hybrid carbon fiber reinforced polymer (CFRP) composite triboelectric device is fabricated, which employs a curved upper copper electrode and a flat lower polyimide layer, both of which are combined with CFRP materials. This device can be used as a triboelectric energy harvesting source for self‐powered sensors that can be combined with fiber reinforced composite‐based structures. A voltage up to 300 mV is produced, which can charge a capacitor to 250 mV. The ability to combine triboelectric and CFRP materials provides a new approach to integrate energy harvesting into engineering structures and manufacture robust harvesting devices.

With the diminution of the energy sources and the need for using cleaner energy, alternatives must be found. In addition, the desire for energy sources to supply autonomous low-power electronics has led to interest in triboelectric materials. We have fabricated an arch-shaped hybrid carbon fiber reinforced polymer (CFRP) composite based triboelectric device employing a curved upper copper electrode and a flat lower electrode of a polyimide that are both combined with CFRP materials. This device aims to be used as a triboelectric harvesting energy source for self-powered sensors that can be combined with fibre reinforced composite based structures. We have been able to produce a voltage up to 300 mV which can charge a capacitor to 250mV. The ability to combine triboelectric and CFRP materials provides a new approach to integrate energy harvesting into engineering structures and manufacture robust harvesting devices.
