Abstract:
1. A medical treatment device comprising a sensor to detect operating states of a medical treatment device, the sensor comprising: a first electrode arranged between a current path input and a current path output, wherein an electric input signal for powering the medical treatment device is applicable to the current path input, and the current path output is configured to couple to a load of the medical treatment device; a second electrode separated from the first electrode by a first dielectric material, the second electrode comprising a first signal terminal for receiving a first sensor signal; and an impedance element separated from the first electrode by a second dielectric material, the impedance element comprising a second signal terminal for receiving a second sensor signal, wherein the first electrode comprises a cross section perpendicular to a direction of propagation of the electric input signal such that the first electrode and the second electrode are coupled to provide a capacitance as the first sensor signal, and wherein the impedance element is formed as a structured electrode such that the first electrode and the impedance element are coupled to provide an impedance as the second sensor signal.
