Integrating electronics with clothing and the human body to support people's lifestyle is quickly becoming a reality. Some of these electronics, including health sensors, communication devices, and personal electronics, contain the potential to revolutionize life in the future. One of the most demanding aspects of such electronic designs is their power supply systems, which necessitate not only a continuous power supply, but also wearable characteristics and durability, which many conventional power-supply methods have failed to fulfill. The triboelectric nanogenerator (TENG), which depends on static charging between materials, can convert mechanical vibrations into electricity. TENGs are foreseen as a leading candidate to power wearable electronics due to their advantages such as high instantaneous power outputs and efficiency, low cost, ease of fabrication, lightweight, and wearability. This paper is a comprehensive review on the most prominent wearable TENG categories; textiles-based TENGs for clothing applications, footwearincorporated TENG designs, and other TENG accessories. Herein, the most important developments in these categories, with a focus on their materials, fabrication, features, advantages, and drawbacks, are examined. Finally, a detailed analysis is provided on the main challenges impeding the progress of wearable TENGs with the insights into potential improvement techniques, targeting the widespread commercialization of this technology.

Green construction materials developed using renewable resources have become the focus of concurrent research owing to increasing environmental considerations and legislations. However, most of the available literature focus only on load-bearing construction elements. Consequently, little attention has been paid towards non-load-bearing construction elements such as partitioning materials. The present work aims to address this gap by investigating the viability of using the biodegradable bioplastic PLA in combination with yarns spun using banana fibres to manufacture a composite panel intended for temporary partitioning materials used in the construction industry. Pre-tensioned banana yarns were used as the reinforcement while PLA was used as the matrix. The composite panels were manufactured using the compression moulding technique. The effect of process parameters such as moulding temperature and pressure, the effects of the degree of pre-tension and the amount of reinforcing yarn on the performance of the panels were investigated. The optimum moulding conditions were found to be 180oC moulding temperature and 15 tonnes of moulding pressure. Yarn pre-tensioning exhibited a positive effect on the performance of the composite panels. However, increasing the reinforcing yarn percentage caused a degradation of flexural performance of the composite. Finally, the performance was compared against the most widely used partitioning material currently, medium-density fibreboard (MDF). The novel composite panel manufactured at optimum conditions exhibited 52% higher impact strength and 55% higher flexural strength when compared to MDF. The composite panel presented herein has the potential to replace MDF as a better performing material manufactured using renewable resources.
