Abstract

Se dan a conocer un dispositivo y un método para detectar la conductividad electrolítica de un fluido. El dispositivo comprende una batería (1) que tiene un electrodo (2) de oxidación y un electrodo (3) de reducción conectados mediante un material (5 4) hidrófilo y/o poroso o un receptáculo vacío que proporciona una cavidad microfluídica para un fluido (10), activándose dicha batería (1) tras la adición de dicho fluido (10) en la misma y proporcionando energía eléctrica mientras que el fluido (10) impregna por capilaridad dicha cavidad microfluídica; y al menos un instrumento (5) conectado a la batería (1). El instrumento (5) tiene una impedancia equivalente que 10 hace que la batería (1) trabaje en un punto de funcionamiento específico lo que permite determinar o discriminar entre valores de conductividad electrolítica del fluido (10) e incluye medios para cuantificar la conductividad electrolítica del fluido (10), infiriendo de ese modo la conductividad del fluido (10) a partir del rendimiento de la batería (1).
