Abstract
A physiological sensor system is provided for recording electrical measurement signals in an environment which impairs the recording, in particular in a magnetic resonance instrument, having a plurality of measurement electrodes as well as a signal amplifier device, a power supply and an electronic device for signal conversion and signal transmission to an external signal processing and/or control instrument. The measurement electrodes (3, 4, 5, 14, 15, n) and the signal amplifier device (6, 16) are arranged in a first shielded casing (2, 13), and the power supply and the electronic device being arranged in a second shielded casing (9), the signal amplifier device (6, 16) being connected or connectable to the electronic device and the power supply through a shielded and/or twisted-wire cable connection (7, 17).
