“…Conductivity can be regulated from 10 -4 to 10 3 S/cm [88]. Sutka et al demonstrated that PEDOT can be used as both a triboelectric and an electrode material for TENG, which produced ~3 times more power density than TENG with indium tin oxide (ITO) electrodes [89]. Similar to PPy, PEDOT is insolvable but when doped with polystyrene sulfonate (PSS), PEDOT:PSS becomes highly soluble in water.…”

Triboelectric nanogenerators (TENG) are one of the most promising candidates for powering wearable and portable devices. Example TENGs have demonstrated flexibility, light weight, biocompatibility, versatility and good performance. Textiles are a potential substrate onto, or into, which wearable technology is increasingly being incorporated but supplying power remains an enduring challenge. TENGs are a potential textile based mechanical energy harvesting power supply and there has been an increasing effort to combine TENGs with fabrics. A significant challenge exists in the integration without losing the performance of the TENG or the original properties (appearance, breathability, washability, and durability) and feel of the textile. Various approaches towards the realisation of textile-based TENGs (T-TENGs) have been demonstrated. Depending on its structure, T-TENGs can be divided into two main types, fabric-based TENG and fibre-based TENG. The fabric-based TENG is composed of conventional and/or modified fabrics, which serve as a substrate and/or a triboelectric material. The fibre-based TENG is fabricated as a single fibre or a collection of interlaced fibres. This paper provides an up to date review of the progress in the research of T-TENGs. The paper covers the basic operating principles, possible operation modes, textile manufacturing methods, material selections, T-TENG fabrication process, surface modification and structural designs. Issues, such as standardised measurement parameters, the challenges and limitations of T-TENG are discussed.

“…In general, the VPP technology can result in a smooth polymer film with a small RMS value, which depends on the film-forming property of organic molecules and the oxidants. Šutka et al developed the PEDOT film with the lowest surface roughness (1.88 nm RMS) by VPP method. Brooke et al produces polypyrrole thin films with (favorably) smooth and uniform morphology, an RMS surface roughness of ca .…”

The polymerization of solid-state small organic molecules generally involving no less three units has been demonstrated to be an important prospect in the field of organic electrons. Presently, owing to the chemical coupling reactions, the polymerization for solid-state small molecules usually involves the complex operations and results in powder polymers and a poor-quality thin-film by spin coating due to their insoluble property in common solvents. The conventional vapor-phase polymerization (VPP) is a powerful technology and has been widely accepted for a high-quality polymer film. However, the VPP is generally used for a limited small organic molecules, but does not apply to a solid-state organic molecules due to the difficulty of vaporization. Herein, we proposed an upgrade vapor phase polymerization strategy, spin-spray coating polymerization method, to overcome the limitation of traditional VPP by spraying of solid-state trithiophenes as precursors in a common low-boiling point organic solvent for a homogeneous conjugated polymer thin-film. The as-fabricated conjugated polymer films show the uniform morphology with the fast and easy polymerization and acceptable thermoelectric performance compared to the traditional chemical and electrochemical oxidation in solution. This spin-spray coating polymerization technique has also been extended to the derivatives of trithiophenes with different alkyl side chains in thiophene, demonstrating the effective strategy for the development of an uniform polymer thin-film with relatively complex structure.

“…For instance, self-powered pH sensors, humidity sensors, biological analyses, identification of toxic pollutants, and temperature sensors have made remarkable progress and are successfully developed. [4][5][6][7] The self-powered nano-sensors can work normally without chemical battery via harvesting mechanical energy from our environment. Unlike other energy sources, mechanical energy has the most potential because it is widely distributed in our environment and it has various forms, including wind, raindrops, and ocean waves.…”

In recent years, triboelectric nanogenerators (TENGs) have developed rapidly and attracted the attention of researchers all over the world. Here, a novel waved-shaped triboelectric nanogenerator using the MgSiO 3 powder (W-TENG) was developed. In this work, polyethylene terephthalate film and MgSiO 3 powder form the triboelectric pairs. W-TENG devices can convert mechanical energy into electric energy. From the results, the maximum output power of a W-TENG can reach 184 µW. Additionally, a W-TENG can generate an open-circuit voltage (V oc ) of 224.26 V, a short-circuit current (I sc ) of 2.74 µA, and a transferred charge of 37.8 nC. Moreover, a W-TENG can serve as a self-powered human motion counter. This design describes a portable TENG device that can promote the self-powered human motion sensor application.
