Information on the applied pressure is critical to the pressure garment treatment. The performance of a close-range radio-frequency pressure measurement method is evaluated. The aim of the measurement is to sense the pressure under pressure garments. The hand-held measurement unit is used to inductively read a passive resonance sensor. The response and the repeatability of a new pressure sensor structure are tested. The performance of the telemetry is tested by altering the distance, angle and alignment between the measurement unit and the sensor. The functioning of the read-out method is tested within the useful frequency range of the sensor. The effects of the measurement environment are studied. According to the results, the tested measurement method is acceptable in this application.
