Mechanical energy harvesting and self-powered electronic applications of textile-based piezoelectric nanogenerators: A systematic review

Nano Energy, Journal Year: 2023, Volume and Issue: 111, P. 108414 - 108414

Published: April 3, 2023

Environmental pollution resulting from fossil fuel consumption and the limited lifespan of batteries has shifted focus energy research towards adoption green renewable technologies. On other hand, there is a growing potential for small, wearable, portable electronic devices. Therefore, considering caused by fuels, drawbacks chemical batteries, applications small-scale wearables devices, development more effective lightweight power source essential. In this context, piezoelectric harvesting technology attracted keen attention. Piezoelectric process that converts mechanical into electrical vice-versa. harvesters can be fabricated in various ways, including through solution casting, electrospinning, melt spinning, spinning techniques. Solution melt-spun filaments used to develop woven, knitted, braided textile-based harvesters. The integration with conventional textile clothing will key enabling realising next generation smart wearable electronics. This review focuses on current achievements based nanogenerators (T-PENGs), basic knowledge about materials mechanism. Additionally, understanding textiles, different fabrication methods T-PENGs, strategies improve performance are discussed subsequent sections. Finally, challenges faced using (T-PENGs) identified, perspective inspire researchers working area presented.

Sweat permeable and ultrahigh strength 3D PVDF piezoelectric nanoyarn fabric strain sensor

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: April 25, 2024

Abstract Commercial wearable piezoelectric sensors possess excellent anti-interference stability due to their electronic packaging. However, this packaging renders them barely breathable and compromises human comfort. To address issue, we develop a PVDF nanoyarns with an ultrahigh strength of 313.3 MPa, weaving different yarns form three-dimensional fabric (3DPF) sensor using the advanced 3D textile technology. The tensile (46.0 MPa) 3DPF exhibits highest among reported flexible sensors. features anti-gravity unidirectional liquid transport that allows sweat move from inner layer near skin outer in 4 s, resulting comfortable dry environment for user. It should be noted sweating does not weaken properties 3DPF, but rather enhances. Additionally, durability comfortability are similar those commercial cotton T-shirts. This work provides strategy developing devices.

Robust Superhydrophobic Composite Fabric with Self‐Healing and Chemical Durability

Small, Journal Year: 2024, Volume and Issue: 20(32)

Published: March 28, 2024

Abstract Superhydrophobic fabrics with multiple functions have become a research hotspot. However, it is challenging to make self‐healing mechanically robust and eco‐friendly superhydrophobic fabrics, which are limited by complex fabrication processes excessive use of environmentally unfriendly solvents during fabrication. Herein, inspired the secretion waxy substance from surface lotus leaves restore water repellency, composite (as‐synthesized PA66/6‐PET@Tico) obtained constructing papillary TiO 2 tentacle‐like fluorinated acrylate polymer (FCB015) coating on polyester‐nylon using two‐step hydrothermal method. The result indicates that PA66/6‐PET@Tico hierarchical micro/nanostructure exhibits excellent properties. Compared FCB015 coated fabric, contact angles (CA) soybean oil rise 172.2° 166.8° 137.4° 98.8°, respectively. After mechanical abrasion, recovers angle (WCA) 165.6° at room temperature. WCA remains higher than 155° after 18 h chemical corrosion. Furthermore, bacterial inhibition rates for Staphylococcus Aureus Escherichia Coli 99.90 98.38%, In this work, new idea proposed designing simple effective coating, expecting promote large‐scale industrial production application functional surfaces.
