摘要：
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.
