Arrangement for compression treatment, in particular compression therapy arrangement and method for operating and monitoring the same

A compression therapy arrangement comprising:

• a compression garment to exert external pressure on a body portion;
• and
• at least one sensor device associated with the compression garment and having at least one pressure sensor for determining the external pressure;
• wherein the pressure sensor comprises:
• at least one pressure circuitry having a sensing impedance that is dependent on the external pressure;
• and
• at least one reference circuitry having a reference impedance that is independent from the external pressure;
• wherein a cumulative signal that is dependent on the external pressure and one or more of an external temperature, an external moisture, and/or external electric fields acting in the vicinity of the sensing impedance is derivable from the pressure circuitry and a reference signal that is independent from the external pressure but dependent on other external influences acting in the vicinity of the reference circuitry;
• wherein the pressure circuitry comprises:
• a sensing capacitor having a capacitance that is dependent on the external pressure;
• wherein the reference circuitry comprises:
• a reference capacitor having a capacitance that is independent from the external pressure;
• and
• wherein the pressure sensor comprises:
• a first at least partially conductive electrode layer;
• a second, at least partially conductive electrode layer;
• and
• a dielectric layer arranged between the first electrode layer and the second electrode layer;
• wherein the electrode layers and the dielectric layer extend in parallel planes;
• and
• wherein the dielectric layer comprises a compressible sensing portion that is obtained by composing the dielectric layer by a gas and a deformable material that is not compressible but conformable such that a change of capacitance of the pressure sensor is also effected by the replacement of air in the sensing portion by the conformable dielectric material.
