This study is based on energy harvesting from vibration and deals with the comparison of different techniques. In the present scenario, energy harvesting has drawn the attention of researchers due to a rapid increase in the use of wireless and small-scale devices. So, there is a huge thirst among scientists to develop permanent portable power sources. In the surroundings, a lot of unutilized energy is wasted which can be collected and used for power generation. Research works have been extensively carried out to develop energy harvesting devices catering to the increasing needs of being efficient and economical. Effective energy harvesting mainly depends on the design of the transducer. Different types of design techniques, material properties, and availability of energy harvesters are reviewed in this paper. The paper aims to explore the advantages and limitations of different energy harvesting principles, advances, and findings of the recent past. This study also discusses some of the key ideas for the enhancement of power output. This paper provides a broad view of the energy harvesting system to the learners, which will facilitate them to design more efficient energy harvesting devices by using different principles.

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.
