On the Development of a Novel Mixed Embroidered-Woven Slot Antenna for Wireless Applications

L. Alonso-González, S. Ver-Hoeye, M. Fernández-García, C. Vázquez-Antuña and F. Las-Heras Andrés, "On the Development of a Novel Mixed Embroidered-Woven Slot Antenna for Wireless Applications," in IEEE Access, vol. 7, pp. 9476-9489, 2019, doi: 10.1109/ACCESS.2019.2891208.

Abstract: A novel mixed embroidered-woven coaxial-fed antenna based on a slotted short-circuited textile integrated waveguide has been designed, manufactured, and experimentally validated for its use in wireless applications. The structure of the antenna and the radiating slot can be manufactured using an industrial loom and a laser prototyping machine, respectively, whereas the conductive vias can be manufactured using a commercial embroidery machine, avoiding subsequent treatments or coating. The manufactured antenna presents a centralworking frequency of 5 GHz and a 20% bandwidth. Good agreement between simulations and measurements has been achieved. In addition, the performance of the antenna has been simulated and analyzed under bent conditions around an air-filled cylinder and using a phantom corresponding to a segment of an arm. This prototype demonstrates the possibility of implementing an alltextile antenna, reducing the backward radiation in comparison to the microstrip-based antennas by the use of a substrate-integrated waveguide topology.

A simulation model of electrical resistance applied in designing conductive woven fabrics

Yuanfang Zhao, Jiahui Tong, Chenxiao Yang, Yeuk-fei Chan and Li Li, “A simulation model of electrical resistance applied in designing conductive woven fabrics,” Textile Research Journal 86(16), Aug. 2018, doi: 10.1177/0040517515590408.

Abstract Numerous studies have performed analyses of knitted fabric integrating conductive yarn in textile-based electronic circuits, some of which established simulative models such as the resistive network model for knitting stitches. Compared to conductive knitted fabrics, limited studies have been presented regarding the resistive theoretical model of conductive woven fabric. In this paper, a simulation model was derived to compute the resistance of conductive woven fabric in terms of the following fabric parameters: structure, density and conductive yarn arrangement. The results revealed that the model is well fitted (P value<0.01) and can predict the resistance of woven fabrics, which makes it possible to estimate the fabric parameters and thus to meet the required resistance. Based on this model, thermal conductive woven fabric with maximum energy management and cost control can be efficiently designed.

CLOUD MANUFACTURING BASED EMBROIDERED WEARABLE ELECTRONICS FOR DAILY ECG MONITORING

Hui Huang, “CLOUD MANUFACTURING BASED EMBROIDERED WEARABLE ELECTRONICS FOR DAILY ECG MONITORING,” Publisher = ? (MTU?), Jan. 2019, doi: ?

Abstract Wearable electronics have been attracting signi�cant attention in various applications such as consumer electronics, healthcare monitoring, localization and navigation and so on. The demand for advanced wearable electronics brings new challenges for the wearable technologies, which impose the limitations of the development of the current wearable electronics. The next generation of wearable electronics calls for special attention on several major challenges, which features more convenient, more energy-efficient and more precise sensing.

In this dissertation, in order to tackle these challenges, three solutions are proposed and the application of ECG monitoring is selected as the validation of our solutions. For the convenience of the wearable ECG monitoring, we propose a new design and manufacturing approach for the embroidered textile circuits to achieve the fully flexible system integrated into cloth, which is called System-on-Cloth (SoCl). A prototype of embroidered ECG sensor is fabricated and tested based on the proposed approach. The testing results of the embroidered ECG sensor show that the cloud manufacturing platform can be considered as an e�ective tool for design and manufacturing the textile circuits based wearable electronics. For the energy e�ciency of the ECG monitoring system, a new ECG signal compression method is proposed for the improvement of energy efficiency via reducing the energy consumption of wireless transmission. The simulation results of the ECG compression show that the new ECG compression method is promising to greatly improve the energy e�ciency for the ECG monitoring system. For the precise ECG sensing, a new denoising method is developed to enable the high quality ECG sensing for the embroidered ECG sensor. The experimental results for the ECG denoising method present a better performance than the state of the art methods.

Wearable Electronics and Smart Textiles: A Critical Review

Stoppa, Matteo; Chiolerio, Alessandro. 2014. "Wearable Electronics and Smart Textiles: A Critical Review." Sensors 14, no. 7: 11957-11992.

Abstract Electronic Textiles (e-textiles) are fabrics that feature electronics and interconnections woven into them, presenting physical flexibility and typical size that cannot be achieved with other existing electronic manufacturing techniques. Components and interconnections are intrinsic to the fabric and thus are less visible and not susceptible of becoming tangled or snagged by surrounding objects. E-textiles can also more easily adapt to fast changes in the computational and sensing requirements of any specific application, this one representing a useful feature for power management and context awareness. The vision behind wearable computing foresees future electronic systems to be an integral part of our everyday outfits. Such electronic devices have to meet special requirements concerning wearability. Wearable systems will be characterized by their ability to automatically recognize the activity and the behavioral status of their own user as well as of the situation around her/him, and to use this information to adjust the systems‘ configuration and functionality. This review focuses on recent advances in the field of Smart Textiles and pays particular attention to the materials and their manufacturing process. Each technique shows advantages and disadvantages and our aim is to highlight a possible trade-off between flexibility, ergonomics, low power consumption, integration and eventually autonomy.
