ABSTRACT
1. TITULO: Anti-Listeria innocua activity of silver functionalised textile prepared with plasma technology

INGLES: Thin layers of silver particles (10–100 Å) were deposited by plasma technology on textiles mainly composed with cotton or polyester in order to obtain antimicrobial properties. The antimicrobial activity against a Listeria innocua strain (LRGIA 01) of these textileswas assessed following a protocol based on the ISO 20743-2005 standard. The number of cultivable bacteria on textiles was then monitored for 24 h. The microbial population after 24 h at 30 °C attained 107 CFU g−1 on control textiles while it did not exceed 103 CFU g−1 on plasma-treated textile. All plasma-treated with silver textiles were anti-Listeria (up to 7 log CFU g−1 decimal reductions of L.innocua populations) and this observation was confirmed by scanning electron microscopy. These textiles could thus have potential applications in food-processing industry to control cross-contaminations by L. monocytogenes.

ESPAÑOL: Las delgadas capas de partículas de plata (10-100 Å) fueron depositadas por la tecnología de plasma en textiles compuestas principalmente con algodón o poliéstercon el fin de obtener propiedades antimicrobianas. La actividad antimicrobiana frente a una cepa de Listeria innocua (LRGIA 01) de estos textiles se evaluó aplicando un protocolo basado en la norma ISO 20743-2005 estándar. El número de bacterias cultivables en los textiles se controló después durante 24 h. La población microbiana después de 24 h a 30 ° C alcanzó 107 UFC g-1 en tejidos de control,mientras que no exceda 103 UFC g-1 en plasma tratado con textil. Todos tratada con plasma con textiles de plata eran anti-Listeria (hasta 7 log ufc g-1 reducciones decimales de las poblaciones de L. innocua) y esta observación fue confirmada por microscopía electrónica de barrido. Estos textiles así podría tener aplicaciones potenciales en la industria de elaboración de alimentos para el control dela contaminación cruzada por L. monocytogenes.

2. TITULO: A novel intelligent textile technology based on silicon flexible skins

INGLES: This paper reports the successful prototype development of a novel intelligent textiletechnology based on the integration of silicon flexible skins with regular textiles. This novel approach enables the embedding of sensing and computational components into textiles without significantly compromising the flexibility and wearable properties. Silicon flexible skins comprised of arrays of silicon islands integrated with boron-doped strain gauges and metal pads were successfullyfabricated using micromachining techniques. Prototypes of intelligent textiles were developed by stitching the silicon flexible skins onto the surface of textiles. The preliminary tests demonstrated excellent durability of the prototypes. The strain experienced by the silicon islands was monitored in real-time using the integrated strain gauges when the prototypes were mechanically deformed. These straindata provide valuable information for the further optimization, and the next stage of development, of this intelligent textile technology.

ESPAÑOL: En este trabajo se reporta el desarrollo de un prototipo exitoso de una tecnología textil inteligente novela basada en la integración de las pieles de silicona flexible con tejidos normales. Este nuevo enfoque permite la incrustación de los sensoresy componentes computacionales en textiles sin comprometer significativamente la flexibilidad y las propiedades de vestir. Silicón pieles flexibles compuestas por conjuntos de islas de silicio integrado con medidores de deformación dopado con boro y pastillas de metal se fabricaron con éxito utilizando técnicas de micro fabricación. Los prototipos de los textiles inteligentes se desarrollaron por...
