A device and method for bioimpedance spectrography corrects for breathing artifacts. A breathing signal is used in conjunction with an impedance signal to adjust for a point in time within a respiratory cycle of a user at which the measurements are made. The correction allows the device to characterize tissue parameters accurately with fewer measurement points.

The invention refers to a sensor arrangement with at least one sensor and a method for monitoring physiological parameters of a person, a textile fabric and a use of a textile fabric. An sensor arrangement is described that is suited to improve signal quality and suppress noise, for instance in remote capacitive sensing of body parameters. To achieve this, certain textile fabrics are used, preferably integrated into textile used in a bed, e.g. the blanket, the bed cover, or the mattress. These textile fabrics allow for a suppression of electromagnetic interference from external sources and can be arranged to avoid charge build-up during measurements, in particular those caused by movements of the person.
