Wearable technology has caught on to progress health and fitness. Simply worn on the body, smart garments can, for instance, track activity. Sensors in functional clothing could also help optimize exercises by monitoring movement sequences. A novel transparent sensor material developed by Fraunhofer ISC enables movement measuring sensors to be printed onto textiles. The innovative material will be presented on IDTechEX Europe at booth F16 in the Estrel Berlin on 27 and 28 April 2016.

Accessories like smart bracelets or smart watches are trending as »personal health coaches«, prompting the bearer to provide for sufficient sleep and activity or a healthy diet. Sensor-embedded textile solutions are a far more challenging and also more expensive approach. Often, function will override appearance. The new materials developed by Fraunhofer ISC might offer a cost-efficient alternative with the extra benefit of more adjustable appearance options.

In cooperation with Fraunhofer ISIT and with support of the project partners from the industry, the new sensor technology will be incorporated into a prototype shirt. This so-called MONI shirt will feature a number of functions but is foremost designed to monitor movement sequences. In an initial step, Fraunhofer ISC has developed novel piezoelectric polymer sensor printing pastes free from toxic solvents while Fraunhofer ISIT has provided the evaluation electronics. The next development steps are planned in close dialogue with the industry partners. They will include field tests on several types of textiles and applications, the further optimization of the electronics as well as wear and washability tests.

The sensor materials coming to use are flexible, transparent and suitable for various applications also beside of smart textiles: They register pressure and deformation and can thus serve as touch or motion sensors. Their sensitivity to temperature deviations further enables monitoring of temperature changes or non-contact interaction, e. g. as proximity sensors.

A simple screen printing process is all it takes to apply the sensor pastes onto textile fabrics or plastic films. Manufacturing encompasses two steps: First, the pattern is printed.

Then, the sensors are subjected to an electric field making the piezolectric polymers align to adopt the targeted pressure sensitivity. The cost-efficient screen printing process is a definite plus when it comes to industrial use. It is the key to mass production of printed sensors on textiles.

Thanks to its transparency and flexibility, the new sensor material offers freedom of design in color and form for textiles and garments. As the sensors are much thinner than a human hair and applicable in whatever form, the wearer will hardly notice them embedded in a garment. There’s yet another benefit: the sensors do not require any power source like a battery. Instead, they harvest energy.

Smart textiles like this could be employed in health care or assisted living. In eldercare, everyday life movement sequences could be monitored and failure noticed. Additionally, it would be possible to monitor body signals of in-patients, such as temperature or breathing. This could be especially beneficial for bedridden patients or babies. Some day, even heart rate surveillance may be possible. Last but not least, functional sensor clothing could achieve cost reductions in the health care system. On top of assuming patient monitoring functions it could add to preventive health care.

In Addition to printed sensors on textiles Fraunhofer ISC shows textilintegrated pressure sensors made of silicone e. g. to measure pressure in shoes.

ALADIN paves the way for circular and demand-driven textile production in Europe

Textile production can be organized sustainably by utilizing short supply chains and preventing overproduction. This can already be achieved today by intelligently connecting and efficiently utilizing existing infrastructure. At the same time, production becomes circular when innovative technologies and materials are used that enable high-quality recycling. The ALADIN research project, launched in May 2026 and co-funded with five million euros under the EU Horizon Europe program, is creating the conditions for this.

TERIS reaches milestone: Fraunhofer consortium develops new standards for tire analysis

In the “TERIS” project, the Fraunhofer institutes ICT, IGD, and IWM—led by the Fraunhofer Institute for Structural Durability and System Reliability LBF—have reached a decisive milestone. For the first time, the teams aim to generate, analyse, and predict tire wear in the laboratory in a standardized and practical manner. As part of this milestone, results are now available on reference abrasion, particle analysis, tribological models, AI-based surface analysis, a test bench concept, and methods for accelerated aging and VOC detection. The tire industry, testing services, and environmental agencies will in future benefit from reliable, rapid laboratory procedures for emissions assessment.

Geotextiles made from recycled materials: GREEN leads the way into the industry

For the industry, recycled materials are creating new opportunities in geotextile production. In the GREEN project, the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE demonstrates that recycled polypro-pylene (PP), polyethylene terephthalate (PET), and high-density polyeth-ylene (HDPE) can be processed into nonwovens, fibers, and membranes that meet industrial requirements. This creates opportunities for use in existing production lines and new value chains in the geotextile market.

2026 general meeting of the Friends and Supporters of RWTH Aachen at ITA

The Friends and Supporters of RWTH Aachen e. V. (proRWTH) looked back on a successful year of support at their 2026 general meeting. The meeting took place at Institut für Textiltechnik (ITA) of RWTH Aachen and was combined with a joint session of the Executive Board and the Administrative Board. Before the general meeting began, participants were given a guided tour of ITA, providing them with fascinating insights into current research and development topics in textile engineering.

Recover™ and Ünteks Group partner to scale recycled cotton in knitwear

Recover(TM), a global producer of low‐impact, high‐quality recycled cotton fiber, announces a new partnership with Ünteks Group, a vertically integrated textile manufacturer based in Turkey. The collaboration focuses on the development of circular knit fabrics and garments, combining Recover’s recycled cotton fiber with Ünteks Group’s integrated capabilities across knitting, dyeing, printing, and garment production.

STEELTOP®: A new benchmark in flat tops for spinning preparation

Modern carding generations achieve higher production performance, placing significantly greater stress on flat tops. Higher cylinder speeds and increased fiber density, combined with tighter carding gaps, create more demanding operating conditions. At the same time, poorer raw material quality and the increased use of recycled materials further intensify these challenges. With STEELTOP®, Trützschler introduces a new full steel flat top series developed for these demanding modern carding processes.

YKK develops concept EXCELLA® zipper tape using nonwoven fabric partially derived from used clothing

YKK Corporation has developed a concept version of its premium EXCELLA® zipper series made from nonwoven fabric sheets created by fiberizing used clothing and other textile materials. Based on a proposal by fashion designer Yuima Nakazato, this item was created as a result of collaboration between Nakazato, Seiko Epson Corporation and YKK. The concept zipper was incorporated as a material component for pieces in the newest YUIMA NAKAZATO Couture Collection, “INFERNO,” which was unveiled in Paris, France on July 8, 2026.
