“…In this regard, TENG is one of the most alternative wind energy conversion strategies on accord of its small scale, low cost, simple fabrication routes, and portability [98]. In order to harvest wind energy, flutter-driven structure [99,100] and rotational structure [101,102] are the two main methods for preparing wind-driven TENG.…”

The increasing needs to power trillions of sensors and devices for the Internet of Things require effective technology to harvest small-scale energy from renewable natural resources. As a new energy technology, triboelectric nanogenerators (TENGs) can harvest ambient mechanical energy and convert it into electricity for powering small electronic devices continuously. In this chapter, the fundamental working mechanism and fundamental modes of a TENG will be presented. It can harvest all kinds of mechanical energy, especially at low frequencies, such as human motion, walking, vibration, mechanical triggering, rotating tire, wind, moving automobile, flowing water, rain drops, ocean waves, and so on. Such variety of energy harvesting methods promises TENG as a new approach for small-scale energy harvesting.

“…Due largely to the potential of highvelocity fluid, self-excited vibrations appear when an elastic object is immersed in a flow field, creating flutter or postflutter motion. 102 Figure 26 illustrates the simulated outputs of using single and multiple layers of aeroelastics VEH. The membrane was sandwiched by rubber, which flutters elastically when an airflow of 13 to 25 ms −1 passes through the EH.…”

Summary Energy harvesting technologies are growing rapidly in recent years because of limitation by energy storage and wired power supply. Vibration energy is abundant in the atmosphere and has the potential to be harvested by different mechanisms, mainly through piezoelectric and electromagnetic means. Various architectural structures were also designed for several operating conditions, namely, resonance frequency and range thereof, acceleration, and energy extraction from several motions. The advantages and disadvantages were elaborated on, and improvements on ideas from current research were discussed in this review.

Energy is the essential requirement of daily life. Due to the diminution of the energy sources, it is necessary develop devices that can harvest the wasted energy that exists in the ambient environment. To address this, triboelectric nanogenerators (TENGs) have been developed as an innovative paradigm for energy harvesting. They can harvest the various forms of mechanical energy, including vibrations, walking, ocean waves, human motion, rain drops, flowing water, the motion of an automobile, wind, rotational energy, and mechanical triggering. TENGs can combine the contact electrification and electrostatic induction for energy conversion and operate on four fundamental modes for conversion of mechanical energy into electrical energy to power small‐scale electronics including mobile phones and sensors. The electrical outputs obtained from TENGs depend on the friction of materials that are selected from the triboelectric series on the basis of their electronegativity and electropositivity. Here, a comprehensive overview of the fundamentals of nanogenerators, various operating modes of TENGs and the design of devices that include them, and the performance improvement of this recently emerged technology is presented.
