Zusammenfassung:Disclosed are sensor arrangements made of a membrane of difluoride polyvinyl of the ferroelectric type, which transform the mechanical energy into electric energy and vice versa, and are lead free, the arrangements comprising a sample of 0.5 mm2 of difluoride polyvinyl membrane located between a first upper plate and a second lower plate, where said first and second plates act as output contacts with a recording area of 7 mm2. Said arrangements are useful for integrating sensors for multiple detections such as temperature, humidity and smoke. La presente invención se refiere a arreglos de sensor elaborados a partir de una membrana de polivinil difloruro, del tipo ferroeléctrico que transforma energía mecánica en eléctrica y viceversa y se encuentran libres de plomo, que se comprenden de una muestra de 0.5 mm2 de membrana de polivinil difloruro colocada entre una primera placa superior y una segunda placa inferior, en donde dichas primera y segunda placas actúan como contactos con una área de registro de 7 mm2. De tal manera que a partir de estos arreglos es posible integrar sensores para múltiples detecciones como es el caso de temperatura, humedad y humo.
