“…Many studies about physical surface modifications have been conducted to improve the output of TENG devices. , Figure (a) shows TENGs with a sandpaper-assisted micropattern on its surface, which easily and cost-effectively enlarged the surface contact area, thus enhancing output performance. A morphology-controllable wrinkled micro/nano hierarchical structure was also developed by integrating multiscale poly(vinyl alcohol) (PVA) architectures (Figure (b)) .…”

Serious climate changes and energy-related environmental problems are currently critical issues in the world. In order to reduce carbon emissions and save our environment, renewable energy harvesting technologies will serve as a key solution in the near future. Among them, triboelectric nanogenerators (TENGs), which is one of the most promising mechanical energy harvesters by means of contact electrification phenomenon, are explosively developing due to abundant wasting mechanical energy sources and a number of superior advantages in a wide availability and selection of materials, relatively simple device configurations, and low-cost processing. Significant experimental and theoretical efforts have been achieved toward understanding fundamental behaviors and a wide range of demonstrations since its report in 2012. As a result, considerable technological advancement has been exhibited and it advances the timeline of achievement in the proposed roadmap. Now, the technology has reached the stage of prototype development with verification of performance beyond the lab scale environment toward its commercialization. In this review, distinguished authors in the world worked together to summarize the state of the art in theory, materials, devices, systems, circuits, and applications in TENG fields. The great research achievements of researchers in this field around the world over the past decade are expected to play a major role in coming to fruition of unexpectedly accelerated technological advances over the next decade.

“…Multistimulus ME energy harvesting device is an important direction for future development. A ME energy harvesting device can be combined with one or more harvesting units, such as triboelectric nanogenerators, 212,213 piezoelectric nanogenerators, 214 and electromagnetic generators. Hybridizing energy harvesters can be developed to harvest power from multiple energy sources, including magnetic fields, vibrations, light, and thermal gradient energy, individually or simultaneously.…”

The wireless sensor network energy supply technology for the Internet of things has progressed substantially, but attempts to provide sustainable and environmentally friendly energy for sensor networks remain limited and considerably cumbersome for practical application. Energy harvesting devices based on the magnetoelectric (ME) coupling effect have promising prospects in the field of self‐powered devices due to their advantages of small size, fast response, and low power consumption. Driven by application requirements, the development of composite with a self‐biased magnetoelectric (SME) coupling effect provides effective strategies for the miniaturized and high‐precision design of energy harvesting devices. This review summarizes the work mechanism, research status, characteristics, and structures of SME composites, with emphasis on the application and development of SME devices for vibration and magnetic energy harvesting. The main challenges and future development directions for the design and implementation of energy harvesting devices based on the SME effect are presented.
