Abstract: The invention proposes a method and device for sensing a liquid that contains positively charged particles and/or negatively charged particles. An electrical field is imposed to the liquid by applying a voltage to a positive electrode and a negative electrode disposed in the liquid, for attracting the negatively charged particles toward the positive electrode to concentrate the negatively charged particles in a first part of the liquid and attracting the positively charged particles toward the negative electrode to concentrate the positively charged particles in a second part of the liquid. A first sensing result is obtained by sensing at least one part of liquid of the first part of the liquid, the second part of the liquid, and a third part of the liquid in which the negatively charged particles and the positively charged particles are deconcentrated. Accordingly, the sensing is conducted in at least one part of liquid in which the concentration of the charged particles is changed.
