Abstract
A capacitive sensor for detecting surface condensation which includes a carrier (2), a metal layer (3) applied to the carrier (2) to form an interdigital structure, a passivation layer (6) formed over the metal layer (3), and a hydrophilic layer (7) applied over the passivation layer (6), where the hydrophilic layer (7) increases a surface tension of the passivation layer (7).
