Seguridad ciclista los leds que se pueden coser en el maillot


Nueve días para el Autonómico de Villena

Detalles Creado en Viernes, 14 Agosto 2015 12:51
El próximo domingo 23 de Agosto se celebrará el Campeonato Autonómico de Triatlón Cross.



La organización, a cargo del Club Triatlón Villena, ha previsto multitud de servicios para los participantes.

Además del Campeonato Autonómico, que se disputará en distáncia SPRINT 750m / 17 km / 4´5 km. ( Todo a 1 vuelta), habrá prueba POPULAR también en la misma distáncia y otra prueba SUPERSPRINT: 350 m / 10,5 km / 2,7 km. (Todo a 1 vuelta), además de la modalidad de EQUIPOS 1000m / 17 km / 9 km (carrera a pie 2 vueltas). El segmento de natación se nadará en la piscina olímpica de la localidad.

Habrá un obsequio especial para los primeros clasificados y para todos los participantes están previstos detalles como una excelente bolsa del corredor, servicio de duchas, masaje al terminar, sorteo de regalos, batido recuperador y avituallamiento sólido y líquido.

Triatlón de la Tinença
4 de Octubre de 2015.
Una prueba en uno de los entornos más bellos de la comunidad valenciana; la Tinença de Benifassa.
El triatlón se inicia en las aguas del pantano de Ulldecona, para nadar 1000m, continuar el ciclismo de CARRETERA durante 36kms subiendo el mítico puerto de Fredes, a 1200m de altura para acabar corriendo 6kms. entre los bonitos y rústicos pueblos de La Pobla de Benifassa y el Bellestar.
Una prueba en la que si quieres, podrás venir acompañado/a y disfrutar del fin de semana con actividades, charla técnica, pasta party etc. y que incluye COMIDA al finalizar la prueba.
Adjuntamos poster y toda la información en este enlace:

Researchers create soft, weavable LED fibers for truly flexible wearable displays

Electronic displays for integration with clothing and textiles are a rapidly developing field in the realm of wearable electronics. However, flexible LEDs designed to form part of an elastic or deformable coating for clothing or apparel – even displays specifically designed to be directly bio-compatible – still rely on a hard substrate on which to layer the appropriate electroluminescent material. Now researchers at the Korea Advanced Institute of Science and Technology (KAIST) have created a fiber-like LED that can be directly knitted or woven to form part of the fabric itself.

"Our research will become a core technology in developing light emitting diodes on fibers, which are fundamental elements of fabrics," said Professor Choi, head of the research team at the School of Electrical Engineering at KAIST. "We hope we can lower the barrier of wearable displays entering the market."


To produce their LED strands, the scientists start with a fiber of polyethylene terephthalate, which they then dip several times into a solution of PEDOT:PSS (poly(3,4-ethylenedioxythiophene) polystyrene sulfonate) and then dry at 130° C (266° F) for 30 minutes to ready it for layering with organic materials. Once dried, the dipped fiber is then re-dipped in a bath of super-yellow (poly-(p-phenylenevinylene) polymer organic LED (OLED)) solution, dried again in an oven, and finally coated with a Lithium Fluoride/Aluminum (LiF/Al) compound.

This process, the researchers claim, is a much more efficient way of applying LED materials to small cylindrical structures than any heat-treating method. By carefully adjusting the extraction rate of the fiber from the solution, the researchers say they can control the deposition thickness to within hundreds of thousandths of a nanometer.


The researchers believe their method of producing LED fibers could be an accelerator for the commercialization of wearable displays because inexpensive, automated high-volume production of fibers using such textile manufacturing methods as roll-to-roll processing could be employed. In this way, LED fibers could be mass-produced as easily as nylon or polyethylene fiber is produced today.

"This technology will eventually allow the production of wearable displays to be as easy as making clothes," said Seon-Il Kwon, a member of the KAIST Electrical Engineering team.

The results of this work were recently published in the journal Advanced Electronic Materials
