“…They can be made sensitive to various external stimuli, both physical and chemical [9], such as the changes in force [10,11], pressure [12,13], deformation [14,15], temperature [16] or the concentration of specific compounds in body fluids [17], like ion chloride [18] or sweat quantity [19]. Furthermore, it is possible to directly functionalize fabrics with organic polymers in order to realize fully textile electrocardiogram electrodes for the detection of biopotentials [20,21]. Such devices represent a valid tool for the early diagnosis of diseases and monitoring.…”

In recent years, wearable technologies have attracted great attention in physical and chemical sensing applications. Wearable pressure sensors with high sensitivity in low pressure range (<10 kPa) allow touch detection for human-computer interaction and the development of artificial hands for handling objects. Conversely, pressure sensors that perform in a high pressure range (up to 100 kPa), can be used to monitor the foot pressure distribution, the hand stress during movements of heavy weights or to evaluate the cyclist’s pressure pattern on a bicycle saddle. Recently, we developed a fully textile pressure sensor based on a conductive polymer, with simple fabrication and scalable features. In this paper, we intend to provide an extensive description on how the mechanical properties of several fabrics and different piezoresistive ink formulation may have an impact in the sensor’s response during a dynamic operation mode. These results highlight the complexity of the system due to the presence of various parameters such as the fabric used, the conductive polymer solution, the operation mode and the desired pressure range. Furthermore, this work can lead to a protocol for new improvements and optimizations useful for adapting textile pressure sensors to a large variety of applications.

“…The resultant conductive cotton fabric can be used in heating pads, flexible electrodes, or for static protection or sensors [ 5 , 6 , 7 ]. Moreover, researchers have utilized poly(3,4-ethylene dioxythiophene): poly(styrenesulfonate) (PEDOT: PSS) for ECG monitoring [ 2 , 8 ], and some breakthroughs in the study of brain activity [ 9 ] and long-term ECG monitoring [ 10 ] have been achieved using this material. However, the application of these conductive fabrics and polymers are often restricted by their complicated fabrication processes, such as micro-fabrication or chemical processing.…”

We fabricated a type of conductive fabric, specifically single-wall carbon nanotube-coated cotton yarns (SWNT-CYs), for electrocardiography (ECG) signal transmission utilizing a “dipping and drying” method. The conductive cotton yarns were prepared by dipping cotton yarns in SWNTs (single-wall carbon nanotubes) solutions and then drying them at room temperature—a simple process that shows consistency in successfully coating cotton yarns with conductive carbon nanotubes (CNTs). The influence of fabrication conditions on the conductivity properties of SWNT-CYs was investigated. The results demonstrate that our conductive yarns can transmit weak bio-electrical (i.e., ECG) signals without significant attenuation and distortion. Our conductive cotton yarns, which combine the flexibility of conventional fabrics and the good conductivity of SWNTs, are promising materials for wearable electronics and sensor applications in the future.

“…The ink was composed of organic semiconductor and organic solvents only. In previous works [5], this biocompatible polymer covered completely the textile substrate after a dip-coating process without any control on the electrodes geometry [6]. Screen printing process allows controlling precisely the area to be functionalized.…”

The goal of this work was the characterization of textile ECG electrodes produced by screen printing with poly-3,4-ethylenedioxythiophene doped with poly(styrene sulfonate) (PEDOT:PSS) conductive organic polymer. In particular, screen printed ECG electrodes were analyzed in the light of the ANSI/AAMI standard EC 12:2000 to reasonably understand their potentialities for the development of smart garments. In fact, smart garments have to be able to resist to everyday use, including the typical garment maintenance. Simulated washing cycles were performed following the ISO 105-C10:2006 standard, monitoring the variation of the noise and impedance, through bench procedures. Human tests revealed how the ECG signals obtained with screen printed electrodes were comparable to those achievable with disposable gelled Ag/AgCl ones. The high skin-electrode contact impedance of brand new electrodes in dry condition limited their usability, whereas the addition of an electrolyte led to comparable signal quality. Remarkably, washing cycles ameliorated the performance in dry conditions up to acceptable levels. This technique can then be used to create electrodes on finished garments, able to resist to everyday use.
