Sensor, device and method for measuring the pressure of an interface between two bodies

摘要

The present invention relates to a sensor ( 10 ) for sensing the interface pressure between two bodies, the sensor having at least two intercommunicating detection zones ( 11 ), each detection zone being formed inside an inflatable envelope ( 12 ) for interposing between said bodies and having two opposite regions whose spacing apart depends on the interface pressure between said bodies, each detection zone including a detector ( 15 a , 15 b) arranged to deliver information associated with the spacing between the opposite regions ( 12 a , 12 b).
