The apparatus includes a control unit for being operably coupled to a decoupling device that exhibits a drift condition and to the capacitive sensor. The control unit being configured to determine an impedance of the capacitive sensor and to determine a characteristic of the capacitive sensor based on at least the impedance. The control unit being further configured to determine a characteristic of the decoupling device based on the characteristic of the capacitive sensor and to provide an estimated capacitance based on the characteristic of the decoupling device, the estimated capacitance being indicative of the state of the capacitive sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for diagnostics of a capacitive sensor","description":"In at least one embodiment, an apparatus for diagnosing a state of a capacitive sensor is provided.
