Measurement and analysis of pressure at various points on the sole of the foot during gait

A system has been developed to measure the pressure at various points on the sole of the foot during gait. Pressure sensors have been incorporated in the footwear to indicate the pressure exerted by corresponding value of output voltage. This voltage is amplified to a TTL compatible value by the amplifier section. Data from the different sensors are then multiplexed and later digitized. Suitable software has been employed to process the data for normalisation and symbolic representation. Appropriate colour intensities are used to indicate different pressure distributions of the foot.
