A sensor for a contactless electrocardiographic measurement on a person includes a carrier for fastening the sensor on an object, such as a vehicle seat, and at least one electrically flat electrode mounted to the carrier by an elastic element. An inflatable bellows is disposed between the carrier and the electrode, inflation of the bellows deflecting the elastic element and increasing a distance between the electrode and the carrier to thereby urge the electrode toward a person seated on the seat.

Sensor for contactless electrocardiographic measurement

A sensor for contactless electrocardiographic measurement of a person has at least one electrically conductive, planar electrode having a measurement surface facing the person and a connection surface facing away from the person. An electrical terminal for connection with a measurement apparatus is spaced from the connection surface such that the connection surface is only placed in electrical connection with the terminal when pressure of a required magnitude is applied to the measurement. The electrical connection may be achieved by a switching contact disposed between the electrode and the terminal which is brought into contact with both the electrode and the terminal when the electrode is deflected toward the terminal by the pressure. A compressible material is disposed between the electrode and the terminal to allow tuning of the pressure required to achieve electrical contact.

Contactless electrocardiographic measurement sensor

A sensor for contactless electrocardiographic measurement on a person includes a carrier for mounting to a seat, an electrode for registering a measurement signal, a pressure sensor supporting the electrode on the carrier, and moisture and temperature sensors mounted to the carrier to detect conditions adjacent to the electrode and the subject person. The moisture sensor and the temperature sensor may be adjacent to at least one opening in the electrode. A processing unit receives information generated by the pressure sensor, the moisture sensor, and the temperature sensor, and filters the measurement signal based on the information. An acceleration sensor may also be mounted to the carrier and/or electrode and send signals to the processor.
