Abstract
A sensing portion of the tension type smart shoe unit is arranged to extend across the width of thea sole of a wearer so that foot pressure applied through the sole is exerted thereon, and a connection portion of the tension type smart shoe unit is fixed by connection to a connecting portion of a circuit block. Thus, even when the foot pressure exerted is biased to the left or right while the wearer is walking, only a portion where the pressure is biased is not sensed in contrast with a conventional case in which piezoelectric sensors are mounted, but the sensing portion is deformed, and the magnitude of an electrical output signal corresponding to the deformation is calculated using an equation of a relationship with a load. Consequently, the amount of foot pressure may be precisely measured even with a simple configuration.
