Abstract :
A test was conducted of a Hercules Orthoflex capacitive sensor used to measure pressure distribution under the foot for gait analysis and sensory substitution. Maximal nonlinearity for the sensor is 16%, and maximal hysteresis is 10% over the pressure range 0 to 1.3 MPa. Seven transducers in each shoe determine the distribution of pressure.<>
