Abstract

The invention relates to an electrode for biomedical measurements, in particular for measurements for electrical impedance tomography, which permits measurements with as little interference as possible. The electrodes comprise a contact plate, a line driver with a high-impedance signal input and low-impedance line output and a current source, with a current output and a reference point, whereby the contact plate is connected to the high-impedance signal input of the line driver and to the current output of the current source and the line driver and the current source are arranged in the vicinity of the contact plate.
