Abstract

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.
