Abstract
The flexible electroluminescent capacitive sensor system contains an electroluminescent capacitive sensor, a capacitance meter, and an electroluminescence electronic drive. The capacitive sensor contains in order a first barrier layer, a first transparent electrode layer, a phosphor layer, a second electrode layer, a flexible, resilient dielectric layer, and an electrically conductive reference layer. The capacitance meter is electrically connected to the electrically conductive reference layer and either the second electrode layer or the first electrode layer. The electroluminescence electronic drive is electrically connected to the first transparent electrode layer and the second electrode layer. The first electrode layer has a first voltage, the second electrode layer has a second voltage, and the conductive reference layer has a third voltage. The first or second electrodes may be patterned to allow for multiple sensor regions integrated into a single sensor structure.
