<p>An apparatus (10) and method for monitoring pressure between the surface of a body part and a contact surface employ a plurality of pressure sensors (20) disposed in a matrix array between the contact surface and the body part. The sensors (20) produce analog force signals proportional to pressure, and a monitor receives the analog signals. A computer processor receives the output signals from the monitor to create a force profile for the sensor array. This monitoring apparatus (10) and method is used, for example, to fit prothetics, to monitor bed-ridden and wheelchair-bound patients, to reduce pain and sores caused by uneven distribution of pressure and to monitor pressure between a cast (90) and a person. The sensors (20) may be mounted on a single sheet (22) or on strips for positioning along the body, and monitoring is accomplished by multiplexing and digitizing the analog force signals.</p> |
