The plantar pressure systems available on the market, such as Pedar [12] and F-Scan [11], embed high dense of force
sensors to cover the complete plantar area in order to overcome
the acceleration force. Due to the extensive coverage
of the sensors, these systems are highly customized to the
individual foot shape and size, priced over 15,000USD per
piece. Thus, the applications purely depending on pressure
measurement are limited to laboratory usage due to their high
cost.
