SHOE SOLE HAVING FORCE SENSORS

摘要

The invention relates to a shoe sole instrumented to measure forces in three dimensions, comprising devices taking measurements at specific points, each of which are provided with: a sensor (4) comprising a rigid rod (43) with a low diameter, around 0.2 mm to 1 mm, connected by one end thereof to the center of a deformable membrane (41) having a surface area of around 1 mm2 to around 10 mm2, and having stress gauges, said sensor being capable of measuring the three components of the forces to which the rigid rod (43) is subjected; and a feedback plate (6) supporting the sensor (4) that has a surface much higher than that of the membrane (41), around 1 to 3 cm2, the plate (6) being more rigid than the material (23) forming the shoe sole and having a center of symmetry approximately aligned with a symmetry axis (z) for the sensor defined by the axis of the rigid rod (43).
