Abstract
Capacitors with variable capacitance in capacitive measuring devices consist of at least one first element (2), which is provided with electrode areas (1), which by displacement of this element (2) of the capacitor relative to a second element (10) of said capacitor produce predetermined changes in capacitance. Ideally, connections to the electrode areas (1) are made from the front, i.e. not through the substrate (6), which is achieved by the fact that an insulating layer (4), over which conducting strips (3) run, is interrupted at the locations where an electrical contact has to be made between a given electrode area (1a) and the appropriate conducting strip (3a), such that at these contact points (5a) the electrode area (1a) and the conducting strip (3a) lie in direct contact with one other and are capable of conducting electricity. Over or in the same place as the conducting strips (3), if necessary essentially insulated electrically from the conducting strips (3) by an electrically insulating cover coating ( 7), electronic components can be placed on the capacitor element (2). The counter-electrode (10) is located on a carrier (12) such that the substrate (6) and/or the carrier forms at least part of the dielectric (13) of the capacitor.
