Abstract

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.
