Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA LOCALIZACION DE TRUFAS POR MEDIO DE LA DETECCION DE LOS COMPUESTOS VOLATILES EMITIDOS POR ESTAS ULTIMAS. SE DESPLAZA POR ENCIMA DEL SUELO POR LO MENOS UN CAPTADOR QUE COMPRENDE UN MATERIAL POLIMERICO CAPAZ DE PRESENTAR UNA RESISTENCIA ELECTRICA DE MAGNITUD VARIABLE EN FUNCION DE LA COMPOSICION DEL AIRE AMBIENTE EN CUANTO A COMPUESTOS VOLATILES, DE FORMA QUE SE LLEVE UN VOLUMEN DE AIRE CAPTADO EN LA PROXIMIDAD DEL SUELO A BARRER A CADA UNO DE DICHOS CAPTADORES, EN ALIMENTAR ELECTRICAMENTE CADA CAPTADOR POR MEDIO DE UNA CORRIENTE DE INTENSIDAD PREDETERMINADA Y EN MEDIR CONTINUAMENTE UN VALOR REPRESENTATIVO DE LA RESISTENCIA DE DICHO CAPTADOR, Y EN SUMINISTRAR UNA SEÑAL DE MEDIDA PARA PROPORCIONAR UNA INFORMACION REPRESENTATIVA DE LAS VARIACIONES DEL VALOR MEDIDO CAPAZ DE PERMITIR LA LOCALIZACION DE UNA TRUFA. LA INVENCION ES APLICABLE COMO ALTERNATIVA AL USO CONVENCIONAL DE ANIMALES PARA TAL LOCALIZACION.
