Methods and devices for determining salt concentration in a bioliquid

Electronic device and method for determining salt concentration in a bioliquid is disclosed, the method comprising obtaining sensor data comprising first sensor data from a first electrode pair associated with a polymer composition comprising hydrocolloids and having at least some of the bioliquid absorbed therein; determining, based on the sensor data, a first parameter indicative of a first electrical property of the polymer composition; determining, based on the sensor data, a second parameter indicative of a second electrical property of the polymer composition; determining, based on the first parameter and the second parameter, a salt concentration of the bioliquid; and providing, via an interface, concentration data indicative of the salt concentration.
