“…Although the electrical output was enhanced, sound reception was still limited in these energy harvesters due to the divergence of spherical waves in air. More recently, Chen et al constructed a TENG integrated with a polymer tube. Low‐frequency sound wave energy was successfully absorbed using electrospun polyvinylidene fluoride (PVDF) nanofibers as the vibrating membrane.…”

IntroductionWith the rapid consumption of global energy, the utilization of new energy is of crucial importance for the development of society and the protection of the ecological environment. [1,2] Triboelectric nanogenerators can effectively collect low-frequency vibration energy and convert it into electrical energy. [3][4][5][6][7][8][9] These nanogenerators are a milestone in the development of new energy research. [9,10] Their discovery has provided new ideas for the collection of many forms of environmental energy, such as vibrational energy, wind energy, hydropower, and bioenergy. [11,12] A sound wave is a special form of mechanical vibration. [13] As a clean, abundant, and sustainable form of energy, sound waves are ubiquitously present in our surroundings, including various sounds from human activities, airport construction sites, and transportation. Unfortunately, most sound wave energy has been wasted because of its very low energy density and the lack of effective technologies for harvesting acoustic energy. [14,15] Energy harvesters operating on the basis of electromagnetic induction or the piezoelectric effect have been proposed to collect various types of vibrational energy, such as vehicle vibration and human movement. [16][17][18][19] However, their application has encountered severe difficulties in regard to acoustic wave energy. The mechanism of power generation using electromagnetic induction is that the conductor in the magnetic field cuts the magnetic induction line to generate induced currents. [20] However, due to the small acoustic energy density and the rapid change in sound pressure, effective cutting of the magnetic line under the action of an acoustic wave force is very difficult for conductors. [21,22] Therefore, using electromagnetic induction to collect acoustic wave energy remains a great challenge. In contrast, piezoelectric materials have good sensitivity to slight disturbances, and most of the previous studies regarding acoustic energy harvesting have concentrated on piezoelectric nanogenerators. [23] However, thus far, such nanogenerators have been limited by low electrical output performance and high structural complexity. [24] Therefore, an advanced acoustic energy harvester with high output performance and good practicability must be proposed soon.An acoustic wave is a type of energy that is clean and abundant but almost totally unused because of its very low density. This study investigates a novel dual-tube Helmholtz resonator-based triboelectric nanogenerator (HR-TENG) for highly efficient harvesting of acoustic energy. This HR-TENG is composed of a Helmholtz resonant cavity, a metal film with evenly distributed acoustic holes, and a dielectric soft film with one side ink-printed for electrode. Effects of resonant cavity structure, acoustic conditions, and film tension on the HR-TENG performance are investigated systematically. By coupling the mechanisms of triboelectric nanogenerator and acoustic propagation, a theoretical guideline is provided for improving energy out...

Human beings share the same community in which the usage of energy by fossil fuels leads to deterioration in the environment, typically global warming. When the temperature rises to the critical point and triggers the continual melting of permafrost, it can wreak havoc on the life of animals and humans. Solutions could include optimizing existing devices, systems, and platforms, as well as utilizing green energy as a replacement of non-renewable energy. In this special issue "Artificial Intelligence for Smart and Sustainable Energy Systems and Applications", eleven (11) papers, including one review article, have been published as examples of recent developments. Guest editors also highlight other hot topics beyond the coverage of the published articles.

Wearable electronics for personal healthcare and environment awareness are attracting more and more attention, where continuous energy supply is requisite and still faces great challenge. Here, a self‐powered electronic skin (e‐skin) system with multiple sensations as well as data processing and data visualization is developed. The core component is a hand‐shaped flexible thermoelectric generator functionalized as e‐skin, which not only harvests energy from body heat to supply power for the entire e‐skin system, but also plays a role of multisensory receptor. The e‐skin system is endowed with multifunction of sensing temperature and humidity, perceiving wind and motion, identifying material and monitoring acceleration, as well as displaying the sensing data on a liquid crystal display, all of which are powered by human body heat. The self‐powered flexible e‐skin provides an advantageous approach for applications in repair of skin injury, wearable healthcare devices, and wearable robots.
