SCINT

Activities:

• Consultancy on application ofnanotechnology

• Development RFID-tags and sensors• Development (smart) packaging systems

• Medical (monitoring) devices, 24/7• Renewable energy systems

Technologies and methods tomake textile intelligent

• Make fibers/fabric conductive (for power supply, data-signal transport, sensing) – Treat fabrics (printing, plasma treatment, coating

fibres etc) – Weave conductive yarns – Integrate electronic wiring and components

• Use materials with specific functionalities other thanconductivity: – Anti-microbial – Slow release

– Influence surface properties – Water vapour transport / ventilation – Heat transfer – Sensor functions & RFID tags

NanotechnologyThe unique properties ofnanotechnology originate from:

- small dimensions, enabling highspeed and high functional

density (nanoelectronics, lab-on-chip), small and lightweightdevices and sensors (smart dust),high sensitivity (sensors,nanowires) and special surfaceeffects (such as lotus effect)

- very large surface area, providingreinforcement and catalyticeffects

- quantum effects, such as highlyefficient optical fluorescent

quantum dots

- new molecular structures, with newmaterial properties: highstrength nanotubes, nanofibers andnanocomposites
