VALIDATION OF F-SCAN PRESSURE SENSOR SYSTEM - A TECHNICAL NOTE

This study performed a quantitative validation on a recently developed pressure sensitive transducer system, the F-Scan sensor system. The r esults indicate that the sensor is adequate for determination of press ure distribution under contact conditions with soft materials. The lin ear response of the sensor was up to 1.7 MPa with good homogeneity thr oughout sensor cells. However, the sensor is sensitive to surface cond itions, loading speeds, and temperature. Variations also exist from se nsor to sensor. In order to have accurate measurement, calibration was recommended in actual clinical or experimental conditions prior to us e, including surface contact conditions, loading speeds, and temperatu re environment. In addition, this sensor system is not suitable for ha rd surface contact such as plexiglas.
