Sensing device for sensing a compressive pressure

A sensing device for sensing a compressive pressure applied by a compression bandage or a compression garment, the sensing device comprising:

• a flexible substrate for wearing beneath the compression bandage or the compression garment;
• and
• a compression sensor attached to the flexible substrate, the compression sensor comprising an input and an output and a signal path therebetween,
• wherein the input and the output are arranged such that a sensor signal received by the output varies in dependence on an alignment of the input and the output;
• and
• wherein the alignment of the input and the output varies in dependence on a compressive pressure applied to the compression sensor, the compressive pressure having a component perpendicular to the substrate, and
• wherein the input and the output are configured such that, in response to the compressive pressure, at least one of the input and the output undergoes a displacement, relative to the substrate, in a direction perpendicular to the substrate;
• and wherein said displacement in the direction perpendicular to the substrate varies the alignment of the input and the output.
