Luminous textile for safety applications

Interior designers always have to deal with the decorative and security aspects when thinking about restaurant and hotel decoration. Safety equipments like evacuation lighting have hence to be integrated in special ambiance and usually, this cannot be done in an aesthetic way.

In the PASTA project several technologies will permit Holding Textile Hermès (HTH) to develop a new concept in the fi eld of decorative textiles with security features integration.

More specifi cally, the feasibility will be shown through the development of an evacuation lighting directly integrated in a textile for wall covering. This hybridization will hence offer designers, a product with integrated security solutions without alteration of the decorative function.

In the PASTA project, LEDs will be directly inserted in the thickness of the textile using the Diabolo process and an automatic positioning machine. The Diabolo mounted LEDs are connected to a conductive yarn via a simple clipping/gluing step directly in the fabric. Moreover, a dedicated machine developed by CSEM will permit the automation of the process.

The decorative home textile with integrated LEDs will be able to show an emergency exit sign in case of evacuation and this sign will not be visible till it’s lightened.

Manual integration of the Diabolo mounted LEDs in home fabric has already shown the great potential of the PASTA project development for HTH. As can be seen on the pictures below the LEDs are perfectly hidden by the fabric when the device is in turned off state and show high luminosity when powered. The LEDs are connected to metallic wires which are integrated in the fabric in such a way that they are totally invisible, as it is shown on the left picture. Only the LEDs remain visible as a natural part of the fabric, taking no more room than a single thread of the fabric. Metallic wires have been used for the fi rst trials and will be replaced by more robust yarns in a second step. HTH is at this time developing dedicated conductive yarns.

THE PROJECT

AIM of the project

The PASTA project will combine research on electronic packaging and interconnection technology with textile research to realize an innovative approach of smart textile. By introducing new concepts for electronic packaging and module interconnect, a seamless, more comfortable and more robust integration of electronics in textile will be possible. The main technological developments will concentrate on a new concept for bare die integration into a yarn (by means of micromachining), a new interconnect technology based on mechanical crimping, and the development of a stretchable interposer serving as a stress relief interface between the rigid component and the elastic fabric. The technologies will

also be assessed in a functional evaluation and reliability testing program. The proposed solutions for integration of electronics in textile will cover a whole range of components, from ultra-small LEDs to complex multichip modules. Moreover, a system design task will tackle the power distribution and system partitioning aspects to provide a complete solution for integration of a distributed sensor/actuator system in fabric.

INTRODUCTION

Contents of this issue

Welcome to the second issue of the PASTA Newsletter. PASTA is a EC funded project within FP7.

It’s the Pasta project’s ambition to bring both worlds, electronics and textile, closer together to result in a more comfortable, easy manufacturable and reliable combination. Many applications in the consumer, medical or professional markets would warmly welcome such improvements.

This newsletter has the ambition to improve and maintain the dialog between the PASTA Consortium and the development communities, which are working on similar topics, respectively potential customers.

In the time between the fi rst newsletter and this issue, 3 new partners have entered and strengthened the consortium! Fundico supports the project on project management. The other 2 partners, FOV Fabrics and NikeTech, are end-users aiming to integrate the Pasta technologies in their products. More information on the targeted applications can be found in this issue.

In this second issue we present the aim of the Pasta project and give an overview of the demonstrators that will be realized within the project. Additionaly, we give some impressions of dissemination activities Pasta project members participated in. Especially the Flex-Stretch workshop in Berlin at the end of 2011 was one of the major dissemination activities, co-organized by Pasta partners.

Enjoy the reading,

DEMONSTRATORS

Bedlinen for moisture and pressure detection

Over 1.4 million people in Germany currently require nursing care. This number will increase to 4.7 million by 2050. The bedlinen demonstrator is intended to be a tool for a more comfortable and safer living. It will be the base design for larger and smaller products.

The bedlinen demonstrator will be a bed linen or bed toper with integrated sensor-wires and sensor-yarns as well as active electronic parts to control and measure humidity through for example bed wetting and changes in the pattern who and how long a person lay in a specifi c position. Control units will collect the information from the sensor nodes and build the interface for signal and alarm functionality.

The impact of bed sore and decubitus ulcers will be minimized through the integration of a signal and alarm function. As end user the market of hospital and home care are targeted. The benefi t for the users is a soft and comfortable appearance where electronic parts are incorporated in a way not to increase the source of the decubitus. The material mix must comply with regulations for medical devices, like the RL 93/42 EWG and national regulations.

The scope of the demonstrator is to show, fi rst in a lab, then in a hospital environment that we can weave a conductive wire into a bed linen and give a immediate warning to nursery personnel that e.g. someone has wet a bed.

Technical textile for monitoring strain in composites

The ETTLIN demonstrator for the PASTA-project is a technical textile for monitoring and is designed for the use in composite materials. This application combines both product lines - ETTLIN tec and ETTLIN white - and by having a reinforcement textile with integrated sensor function therefore opens up new possibilities for ETTLIN. The product line ETTLIN tec consists out of fabrics with particular properties like electrical conductivity or integrated sensor functions. The product line ETTLIN white covers reinforcement materials.

Composite materials are gaining more and more importance, not only in the fi eld of mobility (automotive industry, aviation…) but also as components in medical industries, architecture or machine parts. These materials consist of a textile structure for reinforcement and resin as a matrix. As composite materials are often used in safety applications they have to fulfi ll high requirements. At the same time the function of the composite components have to be inspected due to stresses and strains that happen during the lifetime of the component.

This inspection can be done either on the surface of the component (e.g. by strain gauges that are glued to the component) or be tests that are destructive. A non-destructive inspection does not exist up to now.

At this point the ETTLIN demonstrator comes into play. This demonstrator is supposed to be used like a reinforcement textile material and should include different sensor materials and special fi bers. These sensor fi bers should detect incoming strains and measure them during the use of the component.

RFID for textile process monitoring

FOV Fabrics AB produces and develops high technology woven fabrics. FOV is a leading manufacturer of fabrics for sport, leisure and fashion. The fabrics meet fashion trends in colour, structure and print. Customer demands for performance characteristics, including durable water repellence, waterproofness, windproofness, breathability, easy care and comfort, are fulfi lled. FOV is also a major producer of technical textiles, they provide fabrics for a variety of end uses. The fabrics range from thin and light release to thick and heavy constructions for robust applications. The fabrics are used by demanding customers world-wide.

FOV’s entire production is carried out in-house, resulting in complete control of the production process. When producing cutting-edge technology fabrics, every detail counts. This is why FOV employs a fully integrated production process, consisting of warping, weaving, dyeing, laminating, coating, fi nishing and a well equipped lab for quality control and product development.

Therefore, within Pasta, FOV wants to make use of the Diabolo technology to integrate RFID tags into the textiles. As FOV wants to increase the control over their fabrication processes to further increase the quality of the products, an integrated RFID tag in the textile during the manufacturing of the textile would allow to have more feedback on the processes itself.

An integrated RFID tag, hidden in the yarns of the textile, would allow to uniquely tag the textile. In this way, the Diabolo technology can also be used for anti-counterfeiting. In this way, the origin of the fabric can be guaranteed at all times.

Furthermore, an integrated RFID tag would allow to monitor the whole logistic chain of the fabric after production, especially storage and transport conditions (temperature / humidity) are important parameters.

The success of FOV is based on the ability to manufacture fabrics that combine technical properties with innovative ideas. They work closely with suppliers and customers, combining their knowledge with our skills and creativity in order to ensure that high grade fabrics are brought to the market. Integration of Pasta technology into FOV products is therefore a logical step.

Car seat heater system

A new variable seat heating with integrated micro technology sensors will be developed. A temperature sensor will be integrated in the heating textile, consisting of textile with conductive yarns to generate the heat. The temperature sensor will be used to control the feedback mechanism of the seat heater. Furthermore, integrated seat occupation detection sensors will optimize and control the heat speed and the heat spreading to the area where the user sits. More fl exible heat spreading can be realized in this way.

These types of advanced seat heaters will be used in seats for cars, construction vehicles, disable (electrical) cars, electrical cars etc. The comfort of the user will increase and power consumption of the system will be reduced by a better controlled, more focused heating system. This is particularly important in electrical cars, where power consumption should be limited.

The demonstrator will be realized by integrating electronic components seamlessly into the textile with one of the 3 Pasta technologies (crimp, stretch or crimp package).

More advanced seat heating would mean that Nike Tech could offer both existing and new customers a completely new seat heating concept. It would also mean that it is possible to construct seat heating for new applications in new branches. The market for more advanced seat heaters is huge.
