Progress on wearable triboelectric nanogenerators in shapes of fiber, yarn, and textile

Abstract

Textile has been known for thousands of years for its ease of use, comfort, and wear resistance, which resulted in a wide range of applications in garments and industry. More recently, textile emerges as a promising substrate for self-powered wearable power sources that are desired in wearable electronics. Important progress has been attained in the exploitation of wearable triboelectric nanogenerators (TENGs) in shapes of fiber, yarn, and textile. Along with the effective integration of other devices such as supercapacitor, lithium battery, and solar cell, their feasibility for realizing self-charging wearable systems has been proven. In this review, according to the manufacturing process of traditional textiles starting from fibers, twisting into yarns, and weaving into textiles, we summarize the progress on wearable TENGs in shapes of fiber, yarn, and textile. We explicitly discuss the design strategies, configurations, working mechanism, performances, and compare the merits of each type of TENGs. Finally, we present the perspectives, existing challenges and possible routes for future design and development of triboelectric textiles.

Superstructured α-Fe2O3 nanorods as novel binder-free anodes for high-performing fiber-shaped Ni/Fe battery

“…In the field of energy storage devices, there is a growing demand for high power density and energy density, long cycle lifetime, safety, cost saving, environmental friendly and fast charge/ discharge rate, as well as the advantages of remarkable weavability and superior flexibility [3,[14][15][16][17][18]. Particularly, fiber-shaped energy storage devices (FESDs) have great potential due to the miniature volume, excellent flexibility and textile property [15,[19][20][21][22][23]. Unfortunately, the low energy density restricts their practical applications in daily life [21,22,24].…”

Unfortunately, the low energy density restricts their practical applications in daily life [21,22,24]. Therefore, more and more efforts have been made to enhance the energy density of FESDs.…”

Wearable Skin Sensors and Their Challenges: A Review of Transdermal, Optical, and Mechanical Sensors

“…In response to the external mechanical force or deformation, triboelectric charges are produced on the surfaces due to contact. Once the mechanical force is released, the surfaces gets separated producing a gap between them, and the opposite charges on the surfaces produce a potential difference [171,172]. Therefore, it can also be considered as a mechanical energy harvesting device because it has the capability to monitor touch stimuli without any external power source [173].…”

“…), and triboelectric materials (carbon nanotubes, graphene, polydimethylsiloxane, etc.). [18][19][20] In terms of PENGs, under external force, the central symmetry of crystal structure in these piezoelectric materials is broken, resulting in the generation of a piezoelectric potential ( Figure 3A). 56 The piezoelectric potential drives electrons to flow along an external circuit.…”

“…Among them, energy storage devices include lithium-ion batteries, Zn batteries, and supercapacitors, and so forth. 1,2,[18][19][20][21][22][23][24] Energy conversion devices primarily involve piezoelectric and triboelectric nanogenerators, and solar cells. 5,19,20,25 The hybrid power supplies consist of two typical devices above.…”
