“…Different kinetic energy conversion methods in combination are able to compensate each other, thus boosting the output power. Various types of kinetic (including fluidic) hybridization involving two energy conversion effects have been developed, including piezoelectric–electromagnetic, electrostrictive–electrets, piezoelectric–triboelectric, electromagnetic–triboelectric, piezoelectric–electrostatic, triboelectric–electrostatic, and piezoelectric–electrostrictive . Hybridization involving three kinetic energy conversion effects, piezoelectric–electromagnetic–triboelectric, has also been reported.…”

Energy harvesting technology may be considered an ultimate solution to replace batteries and provide a long-term power supply for wireless sensor networks. Looking back into its research history, individual energy harvesters for the conversion of single energy sources into electricity are developed first, followed by hybrid counterparts designed for use with multiple energy sources. Very recently, the concept of a truly multisource energy harvester built from only a single piece of material as the energy conversion component is proposed. This review, from the aspect of materials and device configurations, explains in detail a wide scope to give an overview of energy harvesting research. It covers single-source devices including solar, thermal, kinetic and other types of energy harvesters, hybrid energy harvesting configurations for both single and multiple energy sources and single material, and multisource energy harvesters. It also includes the energy conversion principles of photovoltaic, electromagnetic, piezoelectric, triboelectric, electrostatic, electrostrictive, thermoelectric, pyroelectric, magnetostrictive, and dielectric devices. This is one of the most comprehensive reviews conducted to date, focusing on the entire energy harvesting research scene and providing a guide to seeking deeper and more specific research references and resources from every corner of the scientific community.

“…Flexoelectric (FE) characteristic exist in all dielectrics materials, where strain gradients allows development polarization even the material is non-piezoelectric [31], [32], shown in Fig.8 a FE materials experiencing polarization when deformed [16]. beam [16] FE polymers are able to sustain great strains which ideal for VENG in wearable applications since human/animal movement requires high train/stroke [31], and considerable FE effects in micro/nano-scale conceivably outperforming PE in some situations [16]. However in order for FE VENG to generate an energetic cycle, pseudo-piezoelectric mode is included in the system which required supplementary bias voltage [31].…”

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.
