“…132 Chitosan is a natural biopolymer that widely exists in marine crustacean shells. The application of such material in TENGs 128,129 could have great impact considering of the huge amount of sea creature shells produced in the food industry every year. Lignin is widely existing in trees and plants that can easily form thin films for using in TENGs, however, studies are limited.…”

A triboelectric nanogenerator (TENG) is a novel technology with applications in many areas, including energy harvesting, self-powered sensing, medication, and electronics. The materials used as triboelectric layers are diverse and include polymers, metals, and inorganic materials. The most commonly used materials are dielectric polymers such as PTFE, FEP, PDMS, and Kapton. Green materials, such as cellulose-based materials, have recently gained increasing interest, and the performance of TENGs using cellulose materials has improved. The material choices are of great importance for TENGs since the triboelectric effects of the materials are fundamental for TENGs. To design a TENG for a particular application, several parameters need to be considered, such as power density, stability, flexibility, and sustainability. This critical review will summarize and evaluate the material choices for TENGs in different applications.

Green and eco‐friendly energy technology are crucial to reduce environmental pollution caused by fossil fuels. Triboelectric nanogenerator (TENG), as an emergency green energy technology, which can get the energy from the surrounding environment and organism. The development of TENG based on degradable materials strongly promote the next‐generation green energy technologies that will effectively avoid pollution and hazards caused by metal and hardly degradable plastic materials. In this review, we summarize the TENG based on degradable materials and its applications. The typical degradable materials for TENG are animal‐based degradable material, plant‐based degradable material, and artificial degradable material. We provide perspectives on the challenges and potential solutions associated with the next‐generation degradable TENG. Beyond the material issue, we highlight the full biodegradable devices that show the healthcare function in vivo.

“…There are normally three methods of converting mechanical kinetic energy to electricity: using triboelectric, [ 1 ] electromagnetic [ 2 ] and piezoelectric effects. [ 3 ] Triboelectric nanogenerators (TENGs), based on a coupling effect of triboelectrification and electrostatic induction, enable the utilization of most forms of mechanical energy, such as wind, [ 4,5 ] human motion, [ 6,7 ] structural vibration, [ 8 ] and ocean waves, [ 9 ] because of their simple fabrication, [ 10 ] light weight, [ 11 ] flexibility, [ 12 ] low cost [ 13 ] and high energy conversion efficiency under low frequency motion. [ 14,15 ] However, most mechanical oscillation in the natural environment involves irregular and low‐frequency movement.…”

Most mechanical energy harvesters produce only small amounts of electrical power from extremely low‐frequency input motions and immediately stop generating electricity when mechanical kinetic energy is exhausted. Here, a steady, long‐lasting and power‐boosted triboelectric nanogenerator is reported that can efficiently harvest from extremely low‐frequency irregular motions of less than 0.1 Hz by utilizing an escapement mechanism and frequency up‐conversion device. The escapement mechanism‐based triboelectric nanogenerator (EM‐TENG) consists of a mechanical energy storage spring, escapement mechanism and a torsional resonator for regular operation and frequency up‐conversion. In addition, the micro‐patterned alternating dielectric surfaces of Nylon and polytetrafluoroethylene (PTFE) and the comb‐type rotator significantly improve the output performance of the rotational EM‐TENG, increasing the current density level approximately 4.2 times compared to flat surfaces. Under an input frequency of 0.067 Hz, the EM‐TENG produces an open circuit voltage of 320 V and a short‐circuit current density of 0.59 mA m‐2. Most importantly, the EM‐TENG can produce long‐lasting and steady output power for 110 s (22 times) under only 5 s of input motion. Therefore, the EM‐TENG might pave the way to effectively harvest energy from extremely low‐frequency motions in nature, such as human motion, structural vibration and ocean waves.
