Beschreibung
Zusammenfassung:	A device and a method for sensing the conductivity of a fluid,The device comprises a battery (1) having an oxidizing electrode (2) and a reducing electrode (3) separated at a distance and connected by a hydrophilic and/or a porous material or an empty receptacle (4) providing a microfluidic cavity for a fluid (10) with a given conductivity, said battery (1) being activated upon the addition of said fluid (10) therein and providing electrical energy while the fluid (10) impregnates by capillarity said microfluidic cavity; and at least one instrument connected to the battery (1). The instrument is configured to interact with the battery (1) and includes means for quantifying the conductivity of the fluid (10) supplied to the battery (10), thereby inferring the conductivity of the fluid (10) from the performance of the battery (1).
