Abstract

Triboelectric Nanogenerators (TENGs) can convert mechanical energy into electricity and harvest this energy.

3D nanocrystalline metal–organic framework materials for the improved output performance of triboelectric nanogenerators

“…[1][2][3][4] Compared with the traditional external fixed energy devices, TENGs with lightweight and easily manufacturable characteristics based on contact electrification and electrostatic induction can effectively convert low-frequency mechanical energy (human movement, wind, and raindrops) in the environment into electrical energy. [5][6][7][8][9][10] However, their low output power density seriously hinders the wide application of TENGs. In order to pursue a high output performance, researchers have explored various methods, including the manufacturing of surface microstructure composites and surface functionalization.…”

Multifunction E-Skin Based on MXene–PA–Hydrogel for Human Behavior Monitoring

“…During actual usage, there are stringent requirements of mechanical properties (e.g., stretchability and toughness and so on) for the hydrogel to fulfill the demands as e-skin. , Stretchability and toughness can ensure the hydrogel to withstand various mechanical deformations and can endow the hydrogel with durability and reliability in continuous mechanical deformation cycles, which determine the life span of flexible devices based on the hydrogel . Over the recent years, plenty of researchers have proposed various approaches to increase the mechanical properties of hydrogels, including double-network hydrogels, , nanocomposite hydrogels, , and topological hydrogels. , For example, Sun et al prepared a poly­(ethylene glycol) dimethacrylate, chitosan, and chitin nanowhisker composite hydrogel whose tensile stress and tensile strain can reach 80% and 0.14 MPa, respectively .…”

Hierarchically spring nanofibrous and wrinkled-structured electrode for highly comfortable wearable triboelectric nanogenerators

“…1 Mobile power is a major challenge in the digital age with exible, stretchable, and portable electronic apparatuses. 2 Among self-powered technologies, like electro-magnetic generators, 3,4 triboelectric nanogenerators (TENGs), [5][6][7][8][9] and piezoelectric nanogenerators, 10,11 TENG with the merit of lightweight, simple structure, and various choices of materials has been considered an effective technique to convert mechanical energy into electricity using electrication and electrostatic induction effects. 2,[12][13][14][15] By contact between two surfaces, opposite triboelectric charges are produced on the two layers.…”

“…They can be applied as motion monitors, touch sensors, and respiratory sensors. 2,14,17,18 For instance, Lan et al 19 fabricated a STENG by PDMS and a composite lm, including AgNWs and metallic molybdenum disulde (MoS 2 ) nanosheets, and used them as a skin-mountable strain sensor. Moreover, Li et al 20 developed a stretchable nanober-based TENG (SNF-TENG) by a breathable and stretchable nanobrous membrane (poly(vinylidene uoride-co-hexauoropropylene) (PVDF-HFP)) and liquid metal and silver akes.…”
