[:es]La degradaci\u00f3n de estructuras de madera por ataques de insectos xil\u00f3fagos es un problema mundial en parte inevitable. Por otro lado, las emisiones ac\u00fasticas (EA) son ondas el\u00e1sticas en materiales s\u00f3lidos causadas por fracturas en macro o microestructuras o por fricci\u00f3n, utilizadas de forma rutinaria como m\u00e9todo est\u00e1ndar para estudiar la fatiga y otros fen\u00f3menos en ingenier\u00eda de materiales. En la madera, hace tiempo que se graban y registran sonidos con el objetivo de identificar el ataque activo de insectos.<\/p>\n\n\n\n

El objetivo de esta l\u00ednea de investigaci\u00f3n es encontrar y desarrollar una t\u00e9cnica de bajo coste y sin contacto, utilizando un array de micr\u00f3fonos MEMS, capaz de detectar y localizar con precisi\u00f3n larvas activas de insectos xil\u00f3fagos en el interior de la madera. El sistema en desarrollo podr\u00eda tambi\u00e9n estar dirigido al control de infecciones en museos y otros lugares donde sea necesaria la protecci\u00f3n de la madera patrimonial, infecciones involuntarias en el comercio internacional de madera, en el ensamblaje y uso de madera infectada y, en todos los casos, y permitir\u00eda la ejecuci\u00f3n de tratamientos selectivos, dirigidos y localizados y la verificaci\u00f3n de su \u00e9xito.[:en]<\/p>\n\n\n\n

The degradation of wood structures by xylophagous insect attacks is a partly unavoidable worldwide problem. On the other hand, acoustic emissions (AE) are elastic waves in solid materials caused by fractures in macro- or microstructures or by friction, routinely used as a standard method to study fatigue and other phenomena in materials engineering. In wood, sounds have long been recorded and recorded for the purpose of identifying active insect attack.

The objective of this line of research is to find and develop a low-cost, non-contact technique, using a MEMS microphone array, capable of detecting and accurately locating active xylophagous insect larvae inside wood. The system under development could also be aimed at infection control in museums and other places where protection of heritage wood is necessary, unintentional infections in the international wood trade, in the assembly and use of infected wood and, in all cases, would allow the execution of selective, targeted and localized treatments and the verification of their success.[:]<\/p>\n\n\n\n
