Abstract: The invention relates to a device with a sensor arrangement, which is able to detect magnetic or magnetized oral administration forms after oral take-up, moreover tracks the dissolution thereof via the reduction or disappearance of the magnetic field of the oral administration form, and with a log function, which records a subjective evaluation on the part of the human wearer of the sensor arrangement during or after the oral take-up.

Abstract: The subject matter of the invention is a detector system for detecting magnetic bodies in the human organism, which comprises at least two sensor assemblies, wherein each sensor assembly has one, two or three anisotropic magnetic resistance sensors, of which the axes of weak magnetization point in different directions in pairs, and each sensor assembly has a spacing of 0.5 to 50 cm from the sensor assembly or the other sensor assemblies, and at least two sensor assemblies are tilted at an angle of 0 to 45° with respect to one another, and in addition a method for detecting the magnetic flux produced by a magnetic body in the human organism, and the use of the detector system according to the invention for detecting swallowed magnetic bodies and the disintegration of the same in the digestive system.
