Abstract

Hidrófono, que comprende: un elemento piezoeléctrico (1) que recibe presión provocada por ondas sonoras que se propagan bajo el agua y transforma éstas en señales eléctricas, un circuito preamplificador (2) para amplificar las señales eléctricas, y un cable (3) conectado a dicho circuito preamplificador (2) para transmitir las señales eléctricas fuera del agua; caracterizado por que el hidrófono comprende además una capa (4) de mezcla de cianoacrilato y bicarbonato de sodio recubierta sobre el circuito preamplificador (2), y una capa adicional (5) de silicona que recubre la superficie de dicha capa (4) de mezcla de cianoacrilato y bicarbonato de sodio.
