The invention relates to a medical diagnostic device () having at least one sensor matrix () for capturing electrical voltage signals at a plurality of locations on the body surface of a person or animal, wherein the diagnostic device () is set up for capturing a signal () representing the position of the sensor matrix () relative to the body of the person or animal, and for determining position information () about the position of the sensor matrix () relative to the body, localized image information () is determined from the voltage signals, and the localized image information () is associated with the position information ().

Medical diagnostic device and method for diagnosing

An ECG device designed as a portable handheld device, with a housing which has a grip area and/or grip elements, wherein the grip area and/or the grip elements are designed to allow the ECG device to be held by an operator, and the ECG device has a sensor area, which is arranged outside the grip area and the grip elements and in which a plurality of ECG sensors in the form of capacitive electrodes is provided. Here, the ECG sensors are at least partially embedded in a foam block secured on the housing, and the ECG sensors are held by the foam block and supported elastically therein.

The invention relates to a sensor system and several method for the capacitive measurement of electromagnetic signals having a biological origin. Such a sensor system comprises a capacitive electrode device (), an electrode shielding element () which surrounds the electrode device () at least in part in order to shield the same () from interfering external electromagnetic fields, and a signal processing device () for processing electromagnetic signals that can be detected by means of the electrode device (). According to the invention, additional shielding means () three-dimensionally surround the electrode device () and the electrode shielding element () at least in part in order to block out interfering external electromagnetic fields. The changes in the electrode capacity of the capacitive sensor system are determined with the aid of several methods which particularly use the inventive sensor system in order to take said changes into account when the test signals are evaluated.
