Moisture sensor for measuring relative moisture comprises hydrophilic part, hygroscopic electrolyte arranged on hydrophilic part, a hydrophobic part and two electrodes

摘要

A moisture sensor comprises a hydrophilic part (5), a hygroscopic electrolyte (1) arranged on the hydrophilic part, a hydrophobic part (8) lying laterally to the electrolyte and two electrodes (3) in contact with the electrolyte. The electrodes are arranged so that they contact the electrolyte via a contact surface (31) which is arranged in a recess (51) of the hydrophilic part.
