Auto-fit mask

A patient interface for sealed delivery of a flow of breathable gas to a patient's airway, the patient interface comprising:

• a sealing structure having a seal surface adapted to contact skin on a patient's face;
• a plurality of capacitive sensors made of textile and weaved into material of the sealing structure, the plurality of capacitive sensors adapted to detect a range of different values of distance of proximity between the seal surface and the patient's face and to generate a sensor signal corresponding thereto;
• a processor configured to determine a sealing condition between the sealing structure and the patient based on the values of distance of proximity of the generated sensor signal;
• and
• a plurality of resistors for the plurality of capacitive sensors and the processor, the plurality of resistors providing a plurality of different sensitivities for the plurality of capacitive sensors for detecting different distances of proximity between the seal surface and the patient's face.
