Abstract
The present invention relates to a wireless, flexible RF (radio frequency) sensor (1) which can sense the ionic concentration and/or solid impurity changes of a liquid contained in a dielectric container independently of each other.
Claims10
An RF sensor (1) used to sense ionic concentration and/or solid impurity changes of a liquid characterized in that
- it is integrated in contact with the outer wall of the dielectric material (A) containing the liquid;
- it radiates radio frequencies into the liquid through the dielectric material and electromagnetically interacts with the liquid and/or solid in the inner volume of the container (A)
- its spectral electromagnetic response changes as a result of the change in the ionic concentration of the liquid;
- its time-dependent electromagnetic response changes as a result of solid impurity;
- it has metal and dielectric layers that can have a pattern;
- and
- has a planar structure.
