Patient monitoring for magnetic resonance imaging

Robert Kowal - Research campus STIMULATE, University Magdeburg;
Jan Kallweit - Institut for Textile Technology at RWTH Aachen University

Magnetic resonance imaging (MRI) is an essential pillar of modern radiology, but it is also susceptible to patient movement.
In this collaborative research project between the Institute of Textile Technology at RWTH Aachen University, ITP GmbH, Incoretex GmbH and the STIMULATE research campus at the University of Magdeburg, novel MRI-compatible pressure measurement mats are being researched. In order to extract information about patient movements during imaging, a matrix of pressure sensors consisting of polymer optical fibres is used, which in turn can be integrated into an intelligent mat.

FOHOS – Mouldable wooden surfaces with integrated, selectively visible, non-contact control elements

Franz Klötzer, Theresa Meixner - STFI Chemnitz

The integration of digital solutions, including integration into smart home systems, is playing an increasingly important role in the area of furniture and interior design. In addition, the trend towards individualisation can be observed throughout the industry. The associated small quantities require new approaches to manufacturing processes and production planning. Particular attention must be paid to surface hygiene, especially in the public sector. The aim of the project was to develop high-quality 3D mouldable real wood surfaces with integrated operating elements. Smart Technical Textiles were developed to achieve the project objectives. This involves a carrier material made of natural fibre-based nonwovens with applied LEDs and textile-based capacitive proximity sensors. The realisation was carried out using embroidery technology. The wood composite components developed consist of wood veneers as a visible surface and a carrier plate. Finally, these composite components were integrated into a piece of furniture to produce a functional demonstrator. The results of the project are innovative wood-textile composite components for the production of high-quality surfaces with integrated actuators and sensors that react to both approach and touch.  The textile capacitive proximity sensors react reliably even when gloves or moist media are used. The project results were visualised in a clear and functional height-adjustable table. The project results therefore form the basis for the development of new innovative wooden elements for furniture and interior design. The R&D project was funded as part of the "Renewable raw materials" funding programme.

Development of textile-integrated sensors for an intelligent ankle orthosis

Kai Ullrich - Imbut GmbH, Greiz

The imbut GmbH sub-project focusses on the development of textile-integrated sensors for the spatially resolved determination of compressive and tensile forces in an intelligent ankle orthosis. This innovation enables users to monitor movements and loads in the joint using sensors and to react to tactile feedback induced by incorrect loading.

The project will utilise foil-based and resistive elastomer sensors that react to pressure and tensile forces by changing their electrical resistance. Techniques for textile integration are being developed for this purpose, such as partial coating or the incorporation of thread-like sensor elements. Key components of the sub-project include the recording of sensor characteristics, the verification of reproducibility, the compensation of environmental influences and the development of manufacturing techniques suitable for series production.

Textile-compatible electrical cables are to be integrated into the textile components of the orthosis to transmit sensor signals and supply power to the sensors and actuators. Appropriate electrical connection techniques, such as solder connections with low-melting solders, are being developed and functional samples tested. Passivation against environmental influences is achieved by coating with polymers, whereby the textile character of the orthosis is largely retained.

The mechanical, thermal and other loads on the sensors and connecting elements are simulated in time-lapse tests under realistic conditions in order to derive measures to increase reliability. A process window determination of the production parameters is intended to ensure rapid transfer to operational practice.

SmartINNO - Skills for Smart Textiles: Identification of required competences in the smart textile industry and development of online training content

Dr. Daniela Zavec - SmartTex-Netzwerk Thüringen;  Lutz Walter - ETB Belgien

The main objective of the SmartINNO project is to facilitate the transfer of knowledge from experts in smart textiles in research organisations and companies to (young) newcomers. The rapid development of smart textiles in various fields such as health and wellness, military, protection, industry and sports requires an update of curricula for vocational and academic education. Based on the findings and results of previous initiatives, projects and activities that have identified sector-specific needs and a lack of skills and knowledge among young textile workers and new entrants, the SmartINNO project aims to prioritise knowledge transfer and support the industry. The main objectives of the project are 1 - Identify the need for smart textiles in the industry, identify current training/educational materials on smart textiles and develop online training materials on smart textiles. 2-Update and test the existing SmartX online platform and develop training workshops 3-Multiplier event and use the platform to strengthen resilience.
