Document Type and Number:
WIPO Patent Application WO/2021/182801
Kind Code:
A1
Abstract:
The present invention relates to a tension-type smart shoe unit capable of foot-pressure measurement, in which a sensing portion of a sensor unit is arranged to extend across the width of the sole of a wearer, so that foot pressure applied through the sole of the wearer is exerted thereon, and a connecting portion of the sensing unit is fixed by connection to a connecting portion of a circuit block, and thus, even when the foot pressure exerted is biased to the left or right while the wearer is walking, rather than only a portion where the pressure is biased being sensed as in the case of the prior art in which a plurality of piezoelectric sensors are mounted, the sensing portion of the sensor unit that consists of a single unit deforms, and the magnitude of an electrical output signal corresponding to the deformation is calculated by an expression of relation of load, thus finally deriving the effect of enabling precise measurement of the amount of foot pressure even with a simple configuration.
