Abstract
A device and a method for detecting living objects for inductive charging devices, the inductive charging device having a resonator coil, which is configured to generate an electromagnetic field, and a plurality of living object sensors, which are configured to detect a living object. The method has steps for determining a critical magnetic field limit of the electromagnetic field by magnetic field limit sensors, the critical magnetic field limit being defined in that a magnetic field strength outside the critical magnetic field limit falls below a limit value; and for detecting a living object within the determined, critical magnetic field limit of the electromagnetic field by the living object sensors.
