Title:
LOAD MEASURING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/158425
Kind Code:
A1
Abstract:
Provided is a load measuring apparatus capable of measuring a partial load acting on each portion of the sole of a foot, and capable of highly accurate and stable measurements with respect to environmental changes such as noise and temperature. This load measuring apparatus 1 comprises: a load sensor unit 2 obtained by forming a plurality of capacitors Ca1-Cd1, Ca2-Cd2 wherein a first sheet-shaped elastic body 21 cyclically provided with a plurality of cavities and a flat second sheet-shaped elastic body 22 serve as dielectric bodies, and a first sheet-shaped conductive elastic body 23, a plurality of second sheet-shaped conductive elastic bodies 24a-24d, and a third sheet-shaped conductive elastic body 25 serve as electrodes; and an electric circuit 3 that has first and second AC output circuits 31, 32 that apply an AC voltage to terminals 23t, 25t of the first and third sheet-shaped conductive elastic bodies 23, 25, and current measurement circuits 33a-33d that measure the AC currents flowing to terminals 24at-24dt of the plurality of the second sheet-shaped conductive elastic bodies 24a-24d, and converts the AC currents into load measurement voltages.
