“…However, these gel electrodes demonstrate reduced performance over time due to moisture evaporation and contamination build-up [46], rendering them unsuitable for long-term wearable applications. Fabric-based dry electrodes exist for wearable therapeutics and have been used in many applications including pain relief [47], stroke rehabilitation [48], [49], improving lymphatic function, and in treatment of urinary incontinence [50]. Materials suitable for making fabric electrodes include conductive yarns, silver polymer paste, and carbon polymer paste [46]- [50].…”

Wearable devices are ideal for personalized electronic applications in several domains such as healthcare, entertainment, sports and military. Although wearable technology is a growing market, current wearable devices are predominantly battery powered accessory devices, whose form factors also preclude them from utilizing the large area of the human body for spatiotemporal sensing or energy harvesting from body movements. E-textiles provide an opportunity to expand on current wearables to enable such applications via the larger surface area offered by garments, but consumer devices have been few and far between because of the inherent challenges in replicating traditional manufacturing technologies (that have enabled these wearable accessories) on textiles. Also, the powering of e-textile devices with battery energy like in wearable accessories, has proven incompatible with textile requirements for flexibility and washing. Although current e-textile research has shown advances in materials, new processing techniques, and one-off e-textile prototype devices, the pathway to industry scale commercialization is still uncertain. This paper reports the progress on the current technologies enabling the fabrication of e-textile devices and their power supplies including textile-based energy harvesters, energy storage mechanisms, and wireless power transfer solutions. It identifies factors that limit the adoption of current reported fabrication processes and devices in the industry for mass-market commercialization.

“…The basis of lymph drainage is to create different pathways through which lymph can flow. Electrodes may be used for this purpose [ 20 , 21 ]. Iontophoresis is one of the most used during rehabilitation treatment for delivery of anti-inflammatory and painkiller medication in the parts of the human body affected by inflammatory processes of the musculoskeletal system [ 22 , 23 , 24 ].…”

Nowadays, after suffering a fracture in an upper or lower limb, a plaster cast is placed on the affected limb. It is a very old and efficient technique for recovery from an injury that has not had significant changes since its origin. This project aims to develop a new low-cost smart 3D printed splint concept by using new sensing techniques. Two rapidly evolving Advanced Manufacturing (AM) technologies will be used: 3D scanning and 3D printing, thus combining engineering, medicine and materials evolution. The splint will include new small and lightweight sensors to detect any problem during the treatment process. Previous studies have already incorporated this kind of sensor for medical purposes. However, in this study it is implemented with a new concept: the possibility of applying treatments during the immobilization process and obtaining information from the sensors to modify the treatment. Due to this, rehabilitation treatments like infrared, ultrasounds or electroshock may be applied during the treatment, and the sensors (as it is showed in the study) will be able to detect changes during the rehabilitation process. Data of the pressure, temperature, humidity and colour of the skin will be collected in real time and sent to a mobile device so that they can be consulted remotely by a specialist. Moreover, it would be possible to include these data into the Internet of Things movement. This way, all the collected data might be compared and studied in order to find the best treatment for each kind of injury. It will be necessary to use a biocompatible material, submersible and suitable for contact with skin. These materials make it necessary to control the conditions in which the splint is produced, to assure that the properties are maintained. This development, makes it possible to design a new methodology that will help to provide faster and easier treatment.

“…Unlike laminated interfaces, printed interfaces ensure that printed e-textiles are fabricated in a single manufacturing process. A screen printed interface layer with an average thickness of 200 µm thick polyurethane film for printing strain gauges, heaters, ECG and EMG electrodes on Optic-White A1656 polyester-cotton fabric currently represents the state of the art [10,11]. At this thickness, the average surface roughness of the fabric is significantly reduced to less than 3 µm However, this interface layer contributes to more than 50 % of the total thickness of the printed e-textile which impacts on the comfort of an e-textile wearer.…”

To achieve durable printed circuits on textiles, it is necessary to print low-cost polymer films that interface the fabric with the printed circuit. The film smooths the surface of the fabric to enable the printing of thin and flexible conductive films on the fabric. When printed, the thickness of the polymer films can dominate the fabric and limit the flexibility of the printed e-textile. This paper investigates the reduction of the polymer film thickness for printed and wearable e-textiles by controlling the thread count of the fabric using different blends of polyester/silk/cotton fabrics. A 50 µm thick polyurethane interface layer with a surface roughness, Ra value of 1.7 µm is reported on a 100% plain weave polyester fabric. The PU thickness is 4 times less than the state of the art and shows more than 80 % reduction in the proportion of interface material to fabric thickness of the printed e-textile. This minimizes the impact of the printed film on the fabric.
