Tongue strength evaluation system and method

A sensing device comprising:

• a sensor plug including a frame portion and a membrane disposed in the frame portion;
• wherein the membrane is movable relative to the frame portion;
• a housing including a sensor entirely contained in the housing;
• wherein the housing is positioned in contact with the sensor plug;
• a chamber defined by the housing in contact with the sensor plug;
• wherein the sensor is in communication with the membrane via the chamber;
• and
• wherein the sensor is configured to sense a movement of the membrane and to generate a sensor output corresponding to a movement of the membrane;
• wherein the sensor plug is attachable to a wall to enclose an aperture defined by the wall;
• wherein the wall defines a passage in communication with the aperture;
• such that with the sensor plug attached to the wall, the chamber is fluidly separated from the passage by the sensor plug;
• the sensor plug defining a sealing groove;
• and
• wherein the sensor plug is attachable via the sealing groove to the wall to enclose the aperture defined by the wall.
