“…When triggered by a linear motor, the typical electrical outputs of the spring-assisted TENG and a reference TENG using an acrylic strip to connect the two blocks are compared in Figure 14b. [132] The schematics of a mechanical amplifier-assisted TENG (MA-TENG) and a SR-TENG are presented in Figure 14e. This is explained by the fact that the connection spring can store part of the impact energy as elastic potential energy, and then release it to induce more cycles of TENG operation.…”

As the world is marching into the era of the internet of things (IoTs) and artificial intelligence, the most vital development for hardware is a multifunctional array of sensing systems, which forms the foundation of the fourth industrial revolution toward an intelligent world. Given the need for mobility of these multitudes of sensors, the success of the IoTs calls for distributed energy sources, which can be provided by solar, thermal, wind, and mechanical triggering/vibrations. The triboelectric nanogenerator (TENG) for mechanical energy harvesting developed by Z.L. Wang's group is one of the best choices for this energy for the new era, since triboelectrification is a universal and ubiquitous effect with an abundant choice of materials. The development of self‐powered active sensors enabled by TENGs is revolutionary compared to externally powered passive sensors, similar to the advance from wired to wireless communication. In this paper, the fundamental theory, experiments, and applications of TENGs are reviewed as a foundation of the energy for the new era with four major application fields: micro/nano power sources, self‐powered sensors, large‐scale blue energy, and direct high‐voltage power sources. A roadmap is proposed for the research and commercialization of TENG in the next 10 years.

“…[2] Its fundamental physics and output characteristics can be attributed to Maxwell's displacement current. [5,[28][29][30] For example, Jiang et al [30] designed a form of spring-assisted TENG for harvesting water wave energy, in which two Cu-PTFE-covered acrylic blocks connected by a spring were placed between two Cu electrodes anchored on two internal walls of a box-like device. [19][20][21][22][23][24][25][26][27] Spring-assisted TENGs are superior for vibration energy harvesting and impact detection at a weak ambient vibration than those without a spring.…”

Vibration is a common mechanical phenomenon and possesses mechanical energy in ambient environment, which can serve as a sustainable source of power for equipment and devices if it can be effectively collected. In the present work, a novel soft and robust triboelectric nanogenerator (TENG) made of a silicone rubber‐spring helical structure with nanocomposite‐based elastomeric electrodes is proposed. Such a spring based TENG (S‐TENG) structure operates in the contact‐separation mode upon vibrating and can effectively convert mechanical energy from ambient excitation into electrical energy. The two fundamental vibration modes resulting from the vertical and horizontal excitation are analyzed theoretically, numerically, and experimentally. Under the resonant states of the S‐TENG, its peak power density is found to be 240 and 45 mW m−2 with an external load of 10 MΩ and an acceleration amplitude of 23 m s−2. Additionally, the dependence of the S‐TENG's output signal on the ambient excitation can be used as a prime self‐powered active vibration sensor that can be applied to monitor the acceleration and frequency of the ambient excitation. Therefore, the newly designed S‐TENG has a great potential in harvesting arbitrary directional vibration energy and serving as a self‐powered vibration sensor.

“…By converting these types of mechanical energy to electrical energy, we can expect for tremendous energy generation. [8][9][10][11][12] Diverse application ranges of TENGs have been proposed and investigated including self-powered systems, [13] wearable devices, [14] self-powered active sensors, [10,15,16] vibration energy harvester, [17][18][19] wind energy harvester. [6] The idea of power generation through triboelectric nanogenerator (TENG) was first introduced by Zhong Lin Wang in 2012 to convert mechanical energy into electrical energy by a conjunction of tribo-electrification and electrostatic induction.…”

Triboelectric nanogenerators (TENGs) can harvest mechanical energy through coupling triboelectric effect and electrostatic induction. Typically, TENGs consist of organic materials, however on account of the potentially wide range of applications of TENGs as the self-powered portable/wearable electronics, biomedical devices, and sensors; semiconductor metal oxide materials can be promising candidates to be incorporating in TENG structure. Here, flexible TENG based on self-organized TiO 2 nanotube arrays (TNTAs) is fabricated via anodization method. The introduced flexible large area nanotubular electrode is employed as the moving electrode in contact with Kapton film in vertical contact separation mode of TENG. The fabricated TENG can deliver output voltage of 40 V with the current density of 1 μA cm À2 . To evaluate the role of nanostructured interface, its performance has been compared to the thin film flat compact TiO 2 electrode. The results of extracted charge measurements under short circuit condition indicate that larger triboelectric charge density formed in TNTA-based electrode (about 110 nC per cycle of press and release) is in comparison to 15 nC in flat TiO 2 electrode. Due to the extensive range of applications of TiO 2 , the introduced structure can potentially be applicable in various types of self-powered systems such as photo-detectors and environmental gas and bio-sensors.
