100% PVDF 3D textiles structures to improve energy harvesting

With a final view to prototyping a textile energy harvesting system, piezoelectric textile structures based on 100% poly(vinylidene fluoride) (PVDF) were developed and characterized. Multifilaments of 246 tex were produced by melt spinning. The mechanical stretching during the process provides PVDF fibers with an optimal β-phase ratio (97%). Some studies have already been carried out on piezoelectric PVDF-based structures as films or textiles. The goal of the study is the investigation of the differences between 2D and 3D woven fabrics structures from piezoelectric PVDF multifilament yarns. The textile structures were poled after the weaving process, and a maximum output voltage of 2.3 V was observed on an angle - through-the-thickness interlock (interlock 3D structure) under compression by DMA tests. Energy harvesting is optimized in a 3D interlock thanks to the stresses of the multifilaments in the thickness. This finding has led to the design of an inner sole prototype from a knitting structure and another structure with piezoelectric fibers outside the plane of the fabric. The prototype is able to harvest energy and the results are consistent with the measurement realized with DMA under dynamic compression close to walking.

The paper presents the results of an experimental study for the realization and testing under static conditions of textile structures used as a support for attachment sensors or electronic functions.

Data-Driven Predictive Maintenance Approach for Spinning Cyber-Physical Production System

The fundamental process of predictive maintenance is prognostics and health management, and it is the tool resulting in the development of many algorithms to predict the remaining useful life of industrial equipment. A new data-driven predictive maintenance and an architectural impulse, based on a regularized deep neural network using predictive analytics, are proposed successfully for ring spinning technology. The paradigm shift in computational infrastructures enormously puts pressure on large-scale linear and non-linear automated assembly systems to eliminate and cut down unscheduled downtime and unexpected stoppages. The sensor network designed for the scheduling process comprises different critical components of the same spinning machine frames containing more than thousands of spindles attached to them. We established a genetic algorithm based on multi-sensor performance assessment and prediction procedure for the spinning system. Results show that it operates with a relatively less amount of training data sets but takes advantage of larger volumes of data. This integrated system aims to prognosticate abnormalities, disturbances, and failures by providing condition-based monitoring for each component, which makes it more accurate to locate the defined component failures in the current spinning spindles by using smart agents during the operations through the neural sensing network. A case study has provided to demonstrate the feasibility of the proposed predictive model for highly dynamic, high-speed textile spinning system through real-time data sensing and signal processing via the industrial Internet of Things.

Development of Smart Textile Materials with Shape Memory Alloys for Application in Protective Clothing.

The latest directions of research on the design of protective clothing concern the implementation of smart materials, in order to increase its protective performance. This paper presents results on the resistance to thermal factors such as flames, radiant heat, and molten metals, which were obtained for the developed smart textile material with shape memory alloys (SMAs). The laboratory tests performed indicated that the application of the designed SMA elements in the selected textile material system caused more than a twofold increase in the resistance to radiant heat (RHTI24 = 224 s) with an increase of thickness of 13 mm (sample located vertically with a load), while in the case of tests on the resistance to flames, it was equal to 41 mm (sample located vertically without a load) and in the case of tests on the resistance to molten metal, it was 17 mm (sample located horizontally).

Compact, Low-Profile and Robust Textile Antennas With Improved Bandwidth for Easy Garment Integration

In this paper, a compact and low-profile proximity-fed textile-based antenna with robust performance and improved bandwidth is proposed for body-area network (BAN) applications. The employed proximity-fed antenna differs from traditional wearable antennas in the sense that it not only exhibits improved bandwidth but also a reduced footprint. The proposed antenna also possesses an extreme robustness when subject to structural deformation and human body loading effects. In addition, the impact of the uncertainty in the dielectric constant (a characteristic associated with most textile material systems) is investigated for the first time. Experimental results show that the proposed proximity-fed antenna outperforms wearable antennas that employ more conventional feeding methodologies. The antenna was fabricated using two different flexible textile-based material systems (i.e., one printed and one embroidered). The advantages and disadvantages of each fabrication approach are discussed. The proposed antenna is characterized in free-space and on a human body, yielding robust performance in both cases.

Ionoskins: Nonvolatile, Highly Transparent, Ultrastretchable Ionic Sensory Platforms for Wearable Electronics

AbstractThe primary technology of next‐generation wearable electronics pursues the development of highly deformable and stable systems. Here, nonvolatile, highly transparent, and ultrastretchable ionic conductors based on polymeric gelators [poly(methyl methacrylate‐ran‐butyl acrylate), PMMA‐r‐PBA] and ionic liquids (IL) are proposed. A crucial strategy in the molecular design of polymer gelators is copolymerization of PMMA and IL‐insoluble low glass transition temperature (Tg) polymers that can be deformed and effectively dissipate applied strains. Highly stretchable (elongation limit ≈850%), mechanically robust (elastic modulus ≈3.1 × 105 Pa), and deformation durable (recovery ratio ≈96.1% after 500 stretching/releasing cycles) gels are obtained by judiciously adjusting the molecular characteristics of polymer gelators and gel composition. An extremely simple “ionic” strain sensory platform is fabricated by directly connecting the stretchable gel and a digital multimeter, exhibiting high sensitivity (gauge factor ≈2.73), stable operation (>13 000 cycles), and nonvolatility (>10 d in air). Moreover, the skin‐type strain sensor, referred to as ionoskin, is demonstrated. The gels are attached to a part of the body (e.g., finger, elbow, knee, or ankle) and various human movements are successfully monitored. The ionoskin renders the opportunity to achieve wearable ubiquitous electronics such as healthcare devices and smart textile systems.

A sustainable development framework for a cleaner multi-item multi-stage textile production system with a process improvement initiative

Abstract One of the most significant sectors in global economy is the textile industry, especially in asian continent. Owing to massive consumption of water in the wet processing operations of the textile sector, this industry is a major creator of effluent water. These effluents severely negatively affect plant photosynthetic function and must be treated prior to discharge into the environment. Reducing this type of hazardous environmental waste is one of the key considerations of lean philosophy. This enhances the consideration of the investments and expenditures made for waste water treatment in production decisions of the textile industry. Along with this, carbon emissions from production systems are more tightly regulated than in the past. Under emissions tax and allocated cap policies, manufacturing setups have to reduce their emissions by upgrading through technological changes and process improvements. In this context, this research provides a sustainable development framework for a cleaner textile production system (in the wet-processing category). The production model is analyzed with regard to environmental and effluent water treatment policies in the multi-stage production system, and optimal batch quantity is determined through a metaheuristic approach. Process reliability can be achieved by improving the production process, for which a discrete investment policy for setup cost reduction and process improvement is suggested, and benefits of these investments to improve environmental protection are studied through comparative analysis. Practical applicability of the proposed production model is highlighted through numerical experiment, sensitivity analysis, and important managerial insights. A trade-off among the investments in various aspects of the system is developed, and the results analysis verify that the introduction of discrete investments for process improvement reduces the effluent water quantity by 12.56% and variable C O 2 emissions cost by 20.98% per batch, thus motivating economic growth and minimizing environmental impacts of the production system.

Understanding the design rules for a nonintrusive, textile, heart rate monitoring system

Background and Objectives: Nonintrusive heart rate (HR) monitoring can be a useful tool for health monitoring. By creating capacitively coupled textile electrodes, a comfortable monitoring system can be integrated into seating or bedding that can monitor HR through clothing. This work empirically studied two factors for a system of this type: the electrode size and the material worn by the subject. Materials and Methods: HR measurements were taken using six different sizes of the rectangular textile electrode with four subjects and the signal-to-noise ratio (SNR) of the signals were analyzed. A further set of experiments were conducted with a single subject and a fixed electrode size where different materials were worn. Results: Electrode size was seen to have a statistically insignificant effect on the collected signal quality. The SNR was also largely unaffected by the worn material type. Conclusion: This study provided empirical data relating to two important factors for nonintrusive, textile, and HR monitoring systems. This data will be helpful for designing a seat-based HR monitoring system or to understand the operational limitations of a system of this type.

Development of Self-Propelled Material Handling System

Material handling system is the vital pillar of manufacturing industries like food, textile, automobile, wood, and other batch type manufacturing system. Research carried out in past shows that material handling accounts for 36% of production cost. A novel material handling system is developed to cut the cost of material transfer and risk of injury. The proposed system consists a mechanism which can self-propel itself and effect the transfer of raw material from one place to another on a shop floor. Since the system is self-propelled, it eliminates external power source in contrast to other material handling systems. The newly developed material handling system utilizes gravitational potential energy of the material loaded on the system to get self-propelled along a straight line. The system returns to original position by retracing the path after unloading the material at the destination. The system not only reduces the energy consumption for material handling but also reduces risk of injury by reducing human interference. It can be used in small and medium size enterprise (SME) to cause improvement in productivity of plant which has limitation on utilization of resources like labour, energy, land and capital.
