Abstract

The invention relates to an electrocardiograph sensor mat (100), the mat (100) comprising a multitude of electrodes (104) for acquiring cardiac signals and a plug (200), wherein the electrodes (104) are connected to the plug (200) by electric wires (102), wherein the wires (102) are segmented by switches (202), wherein the switches (202) are switchable between a closed state and an open state, wherein in the closed state the electrodes (104) are electrically connected to the plug (200) and wherein in the open state the electrodes (104) are electrically isolated from the plug (200).

Claims

1. An electrocardiograph sensor mat, the mat comprising a multitude of electrodes for acquiring cardiac signals and a plug, wherein the electrodes are connected to the plug by electric wires, wherein the wires are segmented by mechanical switches, wherein the mechanical switches are switchable between a closed state and an open state, wherein in the closed state the electrodes are electrically connected to the plug and wherein in the open state the electrodes are electrically isolated from the plug and wherein the mechanical switches comprise removable conducting elements, wherein the elements are fixed to a removable layer. wherein the mechanical switches are adapted for being switched from the closed state to the open state upon a movement of the layer.

3. The mat of claim 1, wherein the switches are operable by pressurized gas, wherein the mat comprises an interface for receiving a connector supplying the gas and for providing a gas connection with the switches.

4. The mat of claim 3, wherein the switches are adapted for being switched from the open state to the closed state upon reception of the gas in a pressurized state.

5. The mat of claim 4, wherein the switches are adapted for automatically switching from the closed state to the open state upon a release of the pressurized gas.

7. The mat of claim 1, wherein the movement comprises a removal of the layer from the mat.

8. The mat of claim 1, wherein the layer is fixable to the mat by fastening means.

9. The mat of claim 8, wherein the fastening means comprise patent fasteners.

10. The mat of claim 1, wherein the segmentation by the switches results in segments, wherein the length of the segments is equal or less than an optimal length, wherein the optimal length is given by a length at which a magnetic resonance scan of an object carrying the mat results

in a magnetic resonance image with artifacts due to the presence of the wires being below a predefined threshold and/or

in a local heating of the electrodes and the segments due to magnetic resonance scan induced Eddy-currents being below a predefined threshold.

11. The mat of claim 1, wherein the mat is comprised in a garment, the garment being wearable by an object for performing the acquisition of the cardiac signals.
