Effect of textile primer layer on screen printed conductors for e-textiles
No full textThis paper reports the influence of screen printed polyurethane (PU) primer layer on the electrical behaviour of screen printed conductors. The PU layer smooths the surface of the textile to allow flexible conductors to be printed on it. By varying the thickness of the PU film, the change in the electrical resistance of the conductors during and after bending was examined. Results show that conductors on un-coated fabrics show greater hysteresis of up to 10% more than conductors on the PU coated fabrics. As the thickness of the PU film increases, the printed conductor experiences more stress and consequently a wider variation in its resistance change during bending

Dispenser printed electroluminescent lamps on textiles for smart fabric applications
No full textFlexible electroluminescent (EL) lamps are fabricated onto woven textiles using a novel dispenser printing process. Dispenser printing utilizes pressurized air to deposit ink onto a substrate through a syringe and nozzle. This work demonstrates the first use of this technology to fabricate EL lamps. The luminance of the dispenser printed EL lamps is compared to screen-printed EL lamps, both printed on textile, and also commercial EL lamps on polyurethane film. The dispenser printed lamps are shown to have a 1.5 times higher luminance than the best performing commercially available lamp, and have a comparable performance to the screen-printed lamps

The data folder contains csv files holding the time / voltage data from
the experiment described in above article.
In those files, a voltage of 0V means that a connection was being made,
1V means it wasn't. Anything in between means it's probably coming or going. It also has connector reliability data for the article and a script for the graphing thereof.</span

Evaluation of a spring-finger based, magnetic connector concept for reliable e-textile interconnects
No full textReliable, impermanent connectors are a significant challenge in the development of e-textile devices, needed to increase their modularity, a key factor in their ability to be repaired or recycled. The combination of spring loaded contacts and magnetic fastenings is a promising option as these components exhibit the small size and mechanical compliance necessary for use in flexible devices.This paper details the evaluation of a 5 pin, spring finger connector held in place by two pairs of 1\,mm thick NdFeB button magnets. The connector is subjected to bending and straightening around a 9 cm diameter to analyse its suitability for use in an e-textile device.The results show that with 1.3mm high springs and a backing with a flexural rigidity of 1.16 × 10-4 Nm², 100\% reliability can be achieved on that test. These results indicate a necessity to use small springs that can easily be flattened. However, their small working range means that they may not be as reliable when connecting to uneven surfaces
Improving the integration of e-textile microsystems' encapsulation by modifying PDMS formulation
No full textElectronic Textiles (e-textiles) enhance traditional fabrics with electronic functionality. When embedded into textiles, flexible electronic circuits need to have reliable functionality but also survive within a textile once it has been integrated. For this, electronic microsystems would be expected by consumers and manufacturers to not alter the typical characteristics the textile inherently has - such as its washability, durability, and manufacturability. Therefore, the choice of packaging substrate for microsystems in a textile must also be hydrophobic and offer minimal expansion when washed; ensuring electronics are undetectable when the textile is handled or cleaned. This paper addresses this by using polydimethylsiloxane (PDMS) as packaging encapsulation and tailoring its fabrication method specifically for textile integration. PDMS of five different base/curing agent mixing ratios were investigated - 5:1, 7:1, 10:1, 15:1, and 20:1. Contact angle measurements and swelling tests with room-temperature distilled water, tap water, detergent, and fabric conditioner solutions show PDMS as a suitable elastomeric encapsulation for electronic textile and wearable applications. Results show that a 20:1, rather than the typical 10:1, mixing ratio offers greater aqueous resistance at smaller dimensions. Having 20:1 compared to 10:1 can reduce swelling by approximately 48% - 45% in water making it more compatible with washing.</p

The data includes csv files containing real and simulated skin impedance data and a few R scripts for analysing and plotting it.
R scripts tested with R 4.2.2, but should be pretty relaxed about what version you're using. Comsol models created with comsol 5.5.0.359 and require using this particular version to work on.</span
