Abstract:
A capacitive sensor comprising a first electrode (3) and a second electrode (4) which are disposed opposite each other in spaced-apart relationship to form a capacitor, the first electrode (3) being disposed on a first substrate (1) and the second electrode (4) on a second substrate (2), the substrates (1, 2) being joined together, and the second substrate (2) including a pressure deformable diaphragm formed in an area of the second electrode (4), wherein an electronic signal processing device (6) for processing measurement signals is disposed in at least one of the substrates (1, 2) just below the electrode (3, 4) disposed thereon, and wherein at least one of the electrodes (3, 4) is formed by a portion of a conductor track of the signal processing device (6, 6a, 6b).
