Embodiment Construction

[0097] In the various figures, the same components are always provided with the same reference numerals, so these components are usually described at once.

[0098] figure 1 A sensor array 20 for a vehicle and a seat 21 according to the prior art for non-contact electrocardiographic measurement of a human body 22 are schematically shown. It can be discerned that the sensor array comprises a matrix-like arrangement of six sensors 23 arranged in a 3×2 matrix in the backrest of the vehicle seat, each sensor having a conductive planar electrode 24 . Furthermore, another electrode is arranged in the seat area of ​​the vehicle seat 21 and thus applies the reference potential of the circuit.

[0099] Each electrode 24 includes a measuring surface 25 facing the human body 22 or its body, and a connecting surface 26 facing away from the human body and opposite to the measuring surface 25 , which is used for connecting with a measuring device 27 . Such as figure 1 As shown, the measu...

Abstract

A sensor for a contactless electrocardiographic measurement of a person includes an electrode formed of a moisture-permeable material and having a measurement surface and an opposite surface. A moisture generator supplies moisture to the opposite surface, and a moisture sensor detects a moisture content of a microclimate at the measurement surface. A controller receives signals from the moisture sensor and activates the moisture generator based upon the signals to control the moisture content. The moisture generator may be a heating element heating a source of moisture; a pump activated pumping liquid from a reservoir to the electrode; an ultrasonic atomizer for atomizing liquid contained in a reservoir; an actuator varying an amount of a liquid-conducting material in contact with liquid contained in a reservoir; or a Peltier element operable to warm and thereby release moisture from a moisture-storing material adjacent to the electrode.

Description

technical field [0001] The invention relates to a sensor for non-contact electrocardiographic measurements on the human body. Furthermore, the invention also relates to a sensor array having a plurality of sensors, and a seat or sofa in a vehicle having a sensor array. Background technique [0002] Measuring the electrical potential or electric field strength on the skin of a human body by an electrocardiogram sensor forms the basis of many medical diagnostic methods. In this way, for example, it is possible to record an electrocardiogram (ECG) or to determine a heart rate from the measured potentials. [0003] In conventional measurement methods for measuring electrical potential on the skin, electrodes are required to be in direct electrical contact with the skin surface. Thereby, an electrically conductive connection is established between the skin (on one side) and the electrode (on the other side). However, it is often very difficult to ensure a good enough electrica...
