Triboelectric Energy Harvesting

Electronic textiles (e-textiles) hold the key for seamless integration of electronic devices for wearable applications. Compared to other flexible substrates, such as plastic films, textiles are, however, challenging substrates to work with due to their surface roughness. Researchers at the University of Exeter demonstrated that using different coating techniques as well as different types of graphene coatings is the key to overcome this challenge. The results of coating selected monofilament textile fibres and woven textiles with graphene are discussed here. These conductive textiles are fundamental components e-textiles, and some applications will be reviewed in this paper. That includes light-emitting devices, touch and position sensors, as well as temperature and humidity sensors. The possibility of triboelectric energy harvesting is also discussed as the next step to realise self-powered e-textiles.

Diamond Thin Films

Recently, there has been considerable interest in electronic device applications of diamond thin films. The chemical properties of diamond is stable. So diamond thin films become very useful if they are used for electronic devices. We consider diamond thin films as blue like emitting devices because diamond has a wide band gap(about 5.5eV). Some light emitting devices have been known [1]. First of all we have been trying to deposit diamond thin films on the large areas. If they deposit on the large areas, light emitting devices may be massproduced.

ZnSe which show a potential application in electronic devices such as photovoltaic devices, light emitting devices and photodetector have been synthesized through a hydrothermal method using ZnCl2 and Se powder as the source. In a typical synthesis, Zn2+ and Se2- ion have been prepared separately and charged into a Teflon-lined stainless steel autoclave. The hydrothermal reaction was conducted at 180 °C for 32 hours. Structural properties of ZnSe are studied by X-ray diffraction (XRD) while the optical properties of ZnSe compound are characterized through ultraviolet–visible spectroscopy (UV-Vis). From the XRD result, pure ZnSe with main XRD peak at 2θ = 27.29°, 45.30°, 53.62°, 65.88°, 72.68° has been observed. The result have been supported by the optical results where absoprtion peak at 460 nm with optical band gap energy (Eg) at 2.5 eV.

Fiber electronics is a key research area for realizing wearable microelectronic devices. Significant progress has been made in recent years in developing the geometry and composition of electronic fibers. In this review, we present that recent progress in the architecture and electrical properties of electronic fibers, including their fabrication methods. We intensively investigate the structural designs of fiber-shaped devices: coaxial, twisted, three-dimensional layer-by-layer, and woven structures. In addition, we introduce remarkable applications of fiber-shaped devices for energy harvesting/storage, sensing, and light-emitting devices. Electronic fibers offer high potential for use in next-generation electronics, such as electronic textiles and smart integrated textile systems, which require excellent deformability and high operational reliability.
