“…In order to find the best suitable condition for the use of the embroidered electrode, as well as its impedance performance in comparison with the commercial electrode, the skin-electrode impedance measurement was conducted under dry and wet conditions. Figure 10a shows the impedance of the embroidered electrode and the knitted electrode suggested in our previous paper [15]. It is evident that embroidered electrodes show superior performance to that of knitted electrodes in the dry conditions.…”

“…The conductive textile is focused on a variety of fields, especially, it is growing in the biotechnology field for smart healthcare monitoring. The textile sensors as substrate devices are likely to contact with the human body in a noninvasive method, such as shirts [11,12], gloves [13], and band type [14,15]. The textile sensor is classified into four significant areas according to the textile structure and pattern as follows: dyeing [16], knitting [17], weaving [18], and embroidery [19].…”

“…Most of the proposed electrodes were made either using commercial electrodes or without an adhesive property. In previous studies, we developed the knit band sensor [15], but it was only able to be worn on the forearm. Additionally, commercial sockets such as a fabric shoulder socket (Martin Bionic, Oklahoma city, OK, USA) [22] and the CJ Socket (CJ socket technology, Beverly city, NJ, USA) [23] were manufactured mixing flexible fabric and rigid parts.…”

Myoelectric prostheses assist users to live their daily lives. However, the majority of users are primarily confined to forearm amputees because the surface electromyography (sEMG) that understands the motion intents should be acquired from a residual limb for control of the myoelectric prosthesis. This study proposes a novel fabric vest socket that includes embroidered electrodes suitable for a high-level upper amputee, especially for shoulder disarticulation. The fabric vest socket consists of rigid support and a fabric vest with embroidered electrodes. Several experiments were conducted to verify the practicality of the developed vest socket with embroidered electrodes. The sEMG signals were measured using commercial Ag/AgCl electrodes for a comparison to verify the performance of the embroidered electrodes in terms of signal amplitudes, the skin-electrode impedance, and signal-to-noise ratio (SNR). These results showed that the embroidered electrodes were as effective as the commercial electrodes. Then, posture classification was carried out by able-bodied subjects for the usability of the developed vest socket. The average classification accuracy for each subject reached 97.92%, and for all the subjects it was 93.2%. In other words, the fabric vest socket with the embroidered electrodes could measure sEMG signals with high accuracy. Therefore, it is expected that it can be readily worn by high-level amputees to control their myoelectric prostheses, as well as it is cost effective for fabrication as compared with the traditional socket.

“…One strategy has been to implement active electrodes or use electrode support structures to acquire EMG signals with the desired fidelity [154,155]. As a different performance metric than other biosignals, pattern recognition/classification accuracies are also important to evaluate and characterize the performance of textile electrodes used specifically in EMG acquisition for prosthetics applications [114]. EMG could benefit from the advantages of textile platforms since they enable data acquisition in more realistic, casual, and out-of-lab settings.…”

Wearable and Flexible Textile Electrodes for Biopotential Signal Monitoring: A review

et al. 2019

Wearable electronics is a rapidly growing field that recently started to introduce successful commercial products into the consumer electronics market. Employment of biopotential signals in wearable systems as either biofeedbacks or control commands are expected to revolutionize many technologies including point of care health monitoring systems, rehabilitation devices, human–computer/machine interfaces (HCI/HMIs), and brain–computer interfaces (BCIs). Since electrodes are regarded as a decisive part of such products, they have been studied for almost a decade now, resulting in the emergence of textile electrodes. This study presents a systematic review of wearable textile electrodes in physiological signal monitoring, with discussions on the manufacturing of conductive textiles, metrics to assess their performance as electrodes, and an investigation of their application in the acquisition of critical biopotential signals for routine monitoring, assessment, and exploitation of cardiac (electrocardiography, ECG), neural (electroencephalography, EEG), muscular (electromyography, EMG), and ocular (electrooculography, EOG) functions.

Nowadays, Electromyography (EMG) signals generated by the amputee's residual limbs are widely used for the control of myoelectric prostheses, usually with the aid of pattern-recognition algorithms. Since myoelectric prostheses are wearable medical devices, the sensors that integrate them should be appropriate for the users'daily life, meeting the requirements of lightness, flexibility, greater motion identification, and skin adaptability. Therefore, this study aims to design and test an EMG sensor for prosthetic control, focusing on aspects such as adjustability, lightness, precise and constant signal acquisition; and replacing the conventional components of an EMG sensor with textile materials. The proposed sensor was made with Shieldex Technik-tex P130 + B conductive knitted fabric, with 99% pure silver plating. EMG data acquisition was performed twice on three volunteers: one with the textile sensor, and other with a commercial sensor used in prosthetic applications. Overall, the textile and the commercial sensor presented total average Signal-to-Noise Ratio (SNR) values of 10.24±5.45 dB and 11.74±8.64 dB, respectively. The authors consider that the obtained results are promising and leave room for further improvements in future work, such as designing strategies to deal with known sources of noise contamination and to increase the adhesion to the skin. In sum, the results presented in this paper indicate that, with the appropriate improvements, the proposed textile sensor may have the potential of being used for myoelectric prosthetic control, which can be a more ergonomic and accessible alternative to the sensors that are currently used for controlling these devices.
