Zp. Luo et al., VALIDATION OF F-SCAN PRESSURE SENSOR SYSTEM - A TECHNICAL NOTE, Journal of rehabilitation research and development, 35(2), 1998, pp. 186-191
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.
