Smart fabrics, generally regarded as smart Textiles are fabrics that have embedded electronics and interconnections woven into them, resulting in physical flexibility that is not achievable with other known electronic manufacturing techniques. Interconnections and components are intrinsic to the fabric therefore are not visible and less susceptible of getting tangled by surrounding objects. Smart fabrics can also more easily adapt to quick changes in the sensing and computational requirements of any specific application, this feature being useful for power management and context awareness. For electronic systems to be part of our day-to-day outfits such electronic devices need to conform to requirements as regards wear-ability, this is the vision of wearable technology. Wearable systems are characterized by their capability to automatically identify the activity and the behavioral status of their wearer as well as of the situation around them, and to use this information to adjust the systems' configuration and functionality. This write-up focused on recent developments in the field of Smart Fabrics and pays particular attention to the materials and their manufacturing techniques.

Electronic textiles, also known as smart textiles or smart fabrics, are one of the best form factors that enable electronics to be embedded in them, presenting physical flexibility and sizes that cannot be achieved with other existing electronic manufacturing techniques. As part of smart textiles, e-sensors for human movement monitoring have attracted tremendous interest from researchers in recent years. Although there have been outstanding developments, smart e-textile sensors still present significant challenges in sensitivity, accuracy, durability, and manufacturing efficiency. This study proposes a two-step approach (from structure layers and shape) to actively enhance the performance of e-textile strain sensors and improve manufacturing ability for the industry. Indeed, the fabricated strain sensors based on the silver paste/single-walled carbon nanotube (SWCNT) layers and buffer cutting lines have fast response time, low hysteresis, and are six times more sensitive than SWCNT sensors alone. The e-textile sensors are integrated on a glove for monitoring the angle of finger motions. Interestingly, by attaching the sensor to the skin of the neck, the pharynx motions when speaking, coughing, and swallowing exhibited obvious and consistent signals. This research highlights the effect of the shapes and structures of e-textile strain sensors in the operation of a wearable e-textile system. This work also is intended as a starting point that will shape the standardization of strain fabric sensors in different applications.

AbstractLightweight computing technologies such as the Internet of Things and flexible wearable systems have penetrated our everyday lives exponentially in recent years. Without a question, the running of such electronic devices is a major energy problem. Generally, these devices need power within the range of microwatts and operate mostly indoors. Thus, it is appropriate to have a self-sustainable power source, such as the photovoltaic (PV) cell, which can harvest indoor light. Among other PV cells, the dye-sensitized solar cell (DSSC) has immense capacity to satisfy the energy demands of most indoor electronics, making it a very attractive power candidates because of its many benefits such as readily available materials, relatively cheap manufacturing methods, roll-to-roll compatibility, easy processing capabilities on flexible substrates and exceptional diffuse/low-light performance. This review discusses the recent developments in DSSC materials for its indoor applications. Ultimately, the perspective on this topic is presented after summing up the current progress of the research. Graphic abstract

Remarkable Progress

Electrospinning is a versatile and viable technique for ultra-thin fiber generation. Remarkable progress has been made with regard to the development of Electrospinning methods and the engineering of Electrospinning Nanofibre to suit or enable different applications. We aim to provide a comprehensive overview of Electrospinning, including principles, methods, materials and applications. We begin with a brief introduction to the early history of Electrospinning, followed by a discussion of its principle and its typical apparatus. Subsequently, we discuss the applications of electrospun Nanofibre, including their use as smart mattresses, filtration membranes, catalytic supports, energy harvesting / conversion / storage components, and photonic and electronic devices, as well as biomedical scaffolds. We highlight the most relevant and recent developments in the application of electrospun Nanofibre by focusing on the most representative examples.

Accounting errors and fraud are common in most businesses, but there is a difference between fraud and misinterpretation of communication or accounting regulations. The role of management in preventing fraud becomes important in the last decades and the importance of auditing in curbing corruption is increasingly revealed. There is a strong connection between fraud and corruption, accelerated by electronic systems and modern platforms.The most recent developments tend to confirm that external auditing is curbing corruption, due to international accounting and auditing standards at national and regional levels. Thus, a better implementation of accounting standards and high quality of external control could prevent errors and fraud in accounting, and reduce corruption, as well.The aim of this paper is to present some particular aspects of errors and fraud in accounting, and how external audit could ensure accuracy and accountability in financial reporting.

Recently, the fabrication of electronics-related components via direct ink writing (DIW) has attracted much attention. Compared to the conventionally fabricated electronic components, DIW-printed ones have more complicated structures, higher accuracy, improved efficiency, and even enhanced performances that arise from well-designed architectures. The DIW technology allows directly print materials on a variety of flat substrates, even a conformal one, well suiting them to applications such as wearable devices and on-chip integrations. Here, recent developments in DIW printing of emerging components for electronics-related applications are briefly reviewed, including electrodes, electronic circuits, and functional components. The printing techniques, processes, ink materials, advantages, and properties of DIW-printed architectures are discussed. Finally, the challenges and outlooks on the manufacture of 3D structured electronic devices by DIW are outlined, pointing out future designs and developments of DIW technology for electronics-related applications. The combination of DIW and electronic devices will help to improve the quality of human life and promote the development of science and society.

This article is devoted to the problem of novelty in embedded art. Exciting possibilities of microelectronics for visual art are considered. Implementations of available microcontrollers, sensors and actuators are given. A new kind of interactions between spectators and artworks with embedded electronics was investigated. Special attention is paid to the effect of emergence, which is generated by this interaction. Computational artwork is being considered in a new unconventional context. An aesthetic difference between the deterministic and nondeterministic algorithms was shown. The combination of acrylic paintings with light-emitting diodes (LEDs) was systematically studied to give useful recommendations for an artistic community. Produced artifacts were demonstrated at exhibitions and were used to teach students at the university and VHS Freiburg, Germany. The results showed a great public interest in embedded electronic systems and a tremendous theoretical and practical perspective for the permanently developing contemporary art.
