Signal recording device for recording a difference signal for the electrical measurement of a vital parameter of a living being and method

摘要

The device (100) has electrodes (120, 120a-12n) contacting with living organism, and supplying electrode signals (130a-130n). An electrode selector (140) selects the electrodes for determining difference signals (110) from the electrodes based on the electrode signals, so that difference signals are deduced from the electrode signals of the selected electrodes. The difference signals are utilized to measure a vital parameter of the living organism, and the electrode selector feeds a reference potential and/or reference signal. A storage unit collects the electrodes with the living organism. The electrodes include a metalized plastic layer, conductive plastic, textile electrode and/or capacitive electrode. An independent claim is also included for a method for determining a difference signal for the electrical measurement of a vital parameter of a living organism.
